Is anyone using this to sense water levels (or just the presence of water)? I'd like to implement a doohickey that monitors water levels in a water storage tank which is not easily accessible. So it must be very reliable, and install-and-forget, as access is a pain in the ass.
- bighi 9y agoI am going to try that this next week. I live in a third world country, and here most days there's no water coming from the pipes. So I am going to try and monitor the water levels in my house. What I bought to do that: A ESP8266 board (it's like an WiFi arduino), and an ultrasound distance sensor. My plan is to point the sensor vertically towards the water. It emits sound and then measures the time it takes for that sound to bounce back. I think I can use to measure the level of water. Then the results will be sent (using MQTT) to my Raspberry Pi that is running Home Assistant.
