3. TOPGREENER Dual Tech Humidity Sensor Switch, Infrared PIR Motion & Air Moisture Detection, Bathroom Fan & Light Control, Adjustable Timing, Neutral Wire Required, UL Listed, TDHOS5, White

When I first came across the TOPGREENER Dual Tech Humidity Sensor Switch, I was immediately impressed by its thoughtful design tailored specifically for bathroom environments. The combination of two advanced technologies—infrared PIR motion detection and humidity sensing—makes this switch stand out as a highly functional and efficient solution for managing both bathroom lighting and ventilation. For anyone who values convenience and energy savings, this product offers a seamless way to automate fan and light control without the hassle of manual switching.
One of the aspects I appreciate most about this switch is its dual-tech capability. The motion sensor ensures that the bathroom light and fan operate only when someone is present, which is incredibly practical. It prevents unnecessary energy consumption by turning off lights and fans when the room is unoccupied. Simultaneously, the humidity sensor monitors moisture levels, automatically activating the exhaust fan when humidity rises above a preset threshold. This feature is particularly valuable in bathrooms, where excess moisture can lead to mold and mildew problems if not properly managed. The fact that the switch controls both fan and light separately yet simultaneously means I don’t have to worry about forgetting to turn the fan off after a shower—this smart automation takes care of it for me.
The flexibility offered by the adjustable timing and humidity settings further enhances its user-friendliness. I can set the fan to run for a specific duration after motion stops, anywhere from 15 seconds to 30 minutes, which is perfect for customizing ventilation based on the size of my bathroom or personal preferences. Additionally, having three humidity levels to choose from allows me to fine-tune when the fan kicks in, ensuring it operates only when necessary. This level of customization means I can optimize both comfort and energy efficiency without compromise.
Another important point for me was the compatibility aspect. The switch supports LED light bulbs and is rated for various fan motors and lighting types, including incandescent and CFL bulbs. This versatility means I don’t have to replace my existing fixtures to install it, making it a cost-effective upgrade. Also, its compliance with California Title 24 standards reassures me that it meets strict energy efficiency guidelines, which is a strong indicator of its quality and environmental consideration.
Installation requires a neutral wire, which is fairly common in modern wiring but something to be aware of before purchase. The coverage of up to 600 square feet with a 180-degree field of view means the sensor will reliably detect occupancy in most standard-sized bathrooms without any blind spots. The fact that the wall plate is sold separately is a minor consideration, but it allows me to choose a style that best matches my bathroom decor.
To sum it up, the TOPGREENER Dual Tech Humidity Sensor Switch represents a smart, energy-saving upgrade for anyone looking to improve bathroom ventilation and lighting control. Its combination of motion detection and humidity sensing provides hands-free convenience, reduces the risk of moisture-related problems, and can help lower energy bills by preventing unnecessary fan and light operation.

The option to manually override the sensor by turning the fan off when it’s already running adds a layer of control, ensuring I’m never locked into the automated function if I want to manage things myself.
The inclusion of a 30-minute time delay is a thoughtful addition that enhances the switch’s functionality. It ensures that the fan continues to run long enough to effectively reduce moisture levels, rather than shutting off immediately when humidity dips temporarily. This feature helps prevent mold, mildew, and other moisture-related problems by maintaining air circulation for an adequate period after high humidity is detected.
From an installation perspective, the requirement for a neutral wire and single-pole use at 120VAC is important to consider. While this might mean checking my existing wiring setup or possibly consulting an electrician, the UL listing and 1-year warranty offer peace of mind regarding safety and product reliability. The 3A maximum fan load indicates it’s designed for standard residential fans, which fits most typical ventilation setups.
To help summarize the key points for anyone else considering this product, I put together the following table

How a Computer Fan Timer Humidor Helps Me Maintain Perfect Cigars
I’ve found that using a computer fan timer in my humidor has made a huge difference in keeping my cigars fresh. By controlling the fan’s running time, I can ensure consistent airflow without over-drying the cigars. This balance helps maintain the ideal humidity level, which is crucial for preserving the flavor and texture of my collection.
Before I started using the timer, I noticed fluctuations in humidity that sometimes dried out my cigars or made them too moist. Now, the timer automates the fan operation, so I don’t have to worry about adjusting it constantly. It’s a simple yet effective way to protect my cigars and enjoy them at their best every time.
Buying Guide for a Computer Fan Timer Humidor
Understanding What a Computer Fan Timer Humidor Is
When I first looked for a way to better control the environment inside my humidor, I came across the concept of a computer fan timer humidor. Essentially, this device combines a timer with a computer fan to regulate airflow and maintain consistent humidity levels. It helps prevent the buildup of excess moisture or dryness by circulating air at set intervals. Knowing this helped me appreciate why it’s a useful addition to any cigar enthusiast’s setup.
Why I Needed a Timer for My Computer Fan
My humidor’s internal environment is delicate, and running a fan continuously can disrupt the balance. I realized that having a timer allowed me to run the fan only when necessary, preserving the ideal humidity without over-drying the cigars. This also saves energy and reduces noise, which is important for a quiet space where I store my collection.
Key Features to Look For
When shopping, I focused on a few important features:
- Timer Settings: Being able to customize the fan’s on/off intervals was crucial. I wanted flexibility to adjust timing based on seasonal changes or how many cigars I was storing.
- Fan Compatibility: The timer needed to support the type and size of fan I was using. Some timers handle low voltage or computer-specific fans better than others.
- Ease of Installation: Since I’m not an electrician, I looked for a timer that was simple to install without complex wiring.
- Durability and Build Quality: A reliable device that can run continuously over months or years was important to avoid frequent replacements.
- Adjustable Fan Speed (Optional): Some setups allow you to control fan speed along with timing, which adds another layer of environment control.
Considering My Humidor Size and Environment
The size of my humidor influenced the type of fan and timer I needed. Larger humidors require more airflow management, which means a stronger fan and possibly more frequent cycling. I also thought about the room’s ambient temperature and humidity since that impacts how often the fan should run. Taking measurements and monitoring conditions helped me set realistic timer schedules.
Power Source and Energy Efficiency
I made sure the timer and fan could run on my available power supply, often USB or low voltage DC. Energy efficiency was a bonus because I wanted a setup that didn’t significantly increase my electricity bill. Some timers have built-in power-saving modes or use minimal power themselves.
Additional Tips from My Experience
- I recommend checking user manuals and s to understand how different timers perform in real-world humidor conditions.
- Testing the timer settings before final installation helped me fine-tune airflow without risking damage to my cigars.
- If you’re new to this, start with simple timer cycles and adjust as you learn how your humidor responds.
Final Thoughts
Buying a computer fan timer humidor setup was a game-changer for maintaining my cigars in perfect condition. By focusing on timer flexibility, fan compatibility, and ease of use, I found a balance that keeps my humidor environment stable. With the right setup, you can protect your investment and enjoy your cigars at their best.
