Welcome to my review of the LILYGO T-Higrow ESP32 Wi-Fi + Bluetooth + DHT11 Soil Temperature and Humidity Sensor Module.
This module is designed to detect soil moisture using a capacitive sensing principle which sets it apart from most of the resistive sensors available in the market. It is a sizeable module, measuring 193.5*29.4mm, and is equipped with both Wi-Fi and Bluetooth capabilities. Let's delve into this product to see how it performs.

When put to the test the LILYGO T-Higrow ESP32 Wi-Fi + Bluetooth + DHT11 Soil Temperature and Humidity Sensor Module proved to be a reliable tool for measuring soil moisture. Its capacitive sensing principle helps to avoid the issue of corrosion that commonly affects resistive sensors, which means that it can last longer. The module's Wi-Fi and Bluetooth capabilities enable users to access soil moisture data remotely, which is convenient. However, it's important to note that it requires additional firmware to work which can be challenging to find.

Simply put the LILYGO T-Higrow ESP32 Wi-Fi + Bluetooth + DHT11 Soil Temperature and Humidity Sensor Module has more pros than cons. On the plus side, the capacitive soil moisture sensor principle makes it more durable than most resistive sensors. It also has Wi-Fi and Bluetooth capabilities, which enable remote access to soil moisture data. However, finding the right firmware to make it work can be tricky and there are no pre-wired measures of battery voltage for battery-operated devices.

To sum up the LILYGO T-Higrow ESP32 Wi-Fi + Bluetooth + DHT11 Soil Temperature and Humidity Sensor Module is an excellent investment for anyone looking to measure soil moisture accurately. Its capacitive sensing principle, coupled with its Wi-Fi and Bluetooth capabilities, make it a reliable tool for gardening enthusiasts and farmers alike. However, potential buyers should be aware that finding the right firmware to make it work may be a bit of a challenge.
