The Tarangify SHT45 Temperature & Humidity Sensor PCB combines the high-accuracy Sensirion SHT45 sensor with a compact rigid PCB designed for easy integration into electronic and IoT systems.
With temperature accuracy of ±0.1°C and humidity accuracy of ±1% RH, the SHT45 is suitable for applications where higher measurement accuracy is required compared with standard temperature and humidity sensors.
The sensor communicates through the I²C interface, making it easy to connect to ESP32, Arduino, Raspberry Pi, STM32, Nordic, RAK Wireless, and other I²C-compatible platforms.
The compact PCB format is particularly suitable for OEM product development, embedded electronics, environmental monitoring, HVAC systems, smart agriculture, weather stations, and data logging applications.
