## Description

Used to detect the presence of water, water leakage Used to measure the water level Supply voltage: 3.3 - 5V DC. Current consumption: less than 20mA Water sensor for Arduino, ESP32, ESP8266, Raspberry Pi, or any 5V or 3.3V microcontroller. Tutorials for Arduino, ESP32, ESP8266 and Raspberry Pi are provided => search for: DIYables Water Sensor

Review: Exactly what I needed - Worked great, hooked them up for a ESP32 meshtastic build. Using these to monitor water levels in my crawlspace to avoid floating away. I have cameras, but that is still a passive approach. These are perfect, easy to solder, and the pins have solid connection. Would order again
Review: Easy to use - Great little water sensors. Have to replace them every 3 months or so inlet environments, even if you use a switched digital output to power it.
