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.

Logging to the cloud
Apr 18, 2021
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
Apr 15, 2021
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
Apr 14, 2021
In this post I test the soil moisture sensor in my PCB design based on the ESP32 touch GPIO, and calibrate it agains known measures of water.
Hardware design
Apr 4, 2021
In this post I present the PCB and design choices for a battery-powered soil moisture sensor using the ESP32 and an on-board status indicator.
