Review: Too small - Sensors are very small
Review: Decent sensors that are probably best used indoors - I used these sensors in a home automation project using an ESP8266 and ESPHome, it work flawlessly and without any problems every time. My main idea was for this to be used outside, which I don't think it was designed for. The cable is quite thin and you'll need to use more industrial adhesive if you plan on using it outside (I used it on my garage door). Time will tell how it holds up, so far so good!
