LilyGO T-Higrow ESP32 Soil Moisture & Temperature Sensor Module with DHT11 & BME280
The LilyGO T-Higrow is an ESP32-based wireless sensor module integrating a capacitive soil moisture sensor, a waterproof DS18B20 temperature probe, and a BME280 environmental sensor for comprehensive soil and ambient monitoring, compatible with Arduino and MicroPython frameworks.
Features
- ESP32 dual-core microcontroller with integrated Wi-Fi & Bluetooth for wireless data logging.
- Capacitive soil moisture sensing principle eliminates electrode corrosion for long-term reliability.
- Integrated DS18B20 waterproof temperature sensor and BME280 for ambient temperature, humidity, and pressure.
- Ultra-low power design with 220 µA sleep current, powered by a single 3.7V Li-ion battery.
- Compact form factor (155mm x 35mm) with T-Grove interface for easy sensor expansion.

The T-Higrow leverages the ESP32’s processing power and wireless connectivity to create a standalone, battery-powered sensor node for precision agriculture and environmental monitoring. Its capacitive soil moisture sensor measures the dielectric constant of the soil, providing a stable reading unaffected by salinity or electrode degradation common in resistive probes.
The module combines this with a sealed DS18B20 for robust soil or liquid temperature measurement and a BME280 for capturing ambient atmospheric conditions. This multi-sensor approach allows for detailed analysis of plant health and microclimate factors. The integrated 4MB flash supports OTA updates and local data buffering, making it suitable for remote, long-term deployment in smart gardens, greenhouses, or research plots.
