Overview
VayuCast is a compact microclimate monitoring device designed for continuous measurement of temperature and relative humidity.
The system uses an ESP32 with an SHT45 sensor for accurate environmental sensing and GSM communication for remote data transmission.
Key Features
- ESP32-based controller
- SHT45 temperature and humidity sensor
- GSM-based remote communication
- OTA firmware updates
- rechargeable 18650 Li-ion battery backup
- compact and portable design
- suitable for remote microclimate monitoring
System Flow
SHT45 Sensor → ESP32 → GSM → Remote Server / Dashboard
OTA support allows firmware updates without physically accessing the device.
