Good for school projects
Bought this for my son's science fair. Works well but instructions could be clearer for total beginners.

Needed extra research
The module itself is fine, but I had to look up online tutorials to understand the wiring diagram fully.

Works perfectly with Uno
Very easy to integrate into my smart home project. The sensitivity knob is responsive and the output is stable.
Q: Is coding knowledge required?
A: Basic understanding of microcontroller programming is recommended to utilize the output signal effectively.
Q: Does it come with jumper wires?
A: Yes, a standard set of female-to-female jumper wires is included in the package.
Q: Is this compatible with 12V systems?
A: No, this module operates strictly on 3.3V to 5V DC. Higher voltage may damage the components.
Q: What is the maximum load it can switch?
A: This is a signal module only. You need a relay or transistor to switch higher loads like lamps.
Q: Can I use this outdoors?
A: The module is not waterproof. It should be housed in a protective enclosure for outdoor use.
