Consistent performance
I have tested this against a multimeter and the switching point is accurate. It handles noise well and doesn't flicker. A staple component for my sensor arrays now.

Perfect for battery monitoring projects
This module works exactly as described. I used it to monitor a 12V lead-acid battery in my solar project. The adjustable threshold is very sensitive and easy to set with a small screwdriver. Highly recommended for hobbyists.

Essential for over-voltage protection
Used this to cut power to a motor driver when the battery drops too low. It saves my LiPo batteries from deep discharge. The potentiometer allows precise calibration. Very satisfied.

Works well for beginners
As someone new to electronics, I found this easy to integrate. Just connect VCC, GND, and Signal. The only reason for 4 stars is that the pins were slightly bent upon arrival, but I fixed them easily.

Reliable and compact
I bought five of these for a robotics club. They are small enough to fit into tight spaces and respond instantly to voltage changes. No false triggers so far. Great product by Xinwei.

Good value, clear instructions needed
The hardware quality is solid and the LED indicator is bright. However, it would be nice if there was a printed diagram on the back for pinout confirmation. Once I figured it out, it worked great with my Arduino Uno.
Q: How do I adjust the voltage threshold?
A: Use a small Phillips head screwdriver to turn the blue potentiometer on the board. Clockwise usually increases the threshold, while counter-clockwise decreases it. Test with a multimeter to calibrate.
Q: Is the output compatible with 5V logic systems?
A: Yes, the digital output is compatible with both 3.3V and 5V logic systems, making it suitable for Arduino, ESP8266, and Raspberry Pi.
Q: What is the maximum current this module can handle?
A: This is a sensing module, not a load switch. It draws very little current (approx. 5mA) for its own operation. It outputs a signal to control other devices like relays or MOSFETs which handle the high current.
Q: Can this module detect AC voltage?
A: No, this module is designed strictly for DC voltage detection. Using it with AC sources may damage the component.
Q: Does this come with jumper wires?
A: The package includes only the voltage detection module. Jumper wires are sold separately, but any standard Dupont wires will work perfectly with the header pins.
