ESP32 Soil Moisture Sensor

In this project I develop a small, battery-powered soil moisture sensor using the ESP32 with an on-board status indicator and data logging to the cloud.

Build Logs

In this post I will implement cloud logging data over WiFi for my ESP32 soil moisture sensor to an InfluxDB database on a remote server.

Using deep sleep

In this post I will implement deep sleep for my soil moisture sensor to periodically wake up to do a reading while maximizing the battery life.

Testing the sensor
