SHT45 Digital Temperature & Humidity Sensor Probe
The SHT45 Sensor Probe is a digital temperature and relative humidity sensor designed for environmental monitoring and embedded applications. It provides typical accuracy of ±0.1°C for temperature and ±1.0% RH for relative humidity. The probe communicates through an I²C interface with a fixed address of 0x44, allowing straightforward integration with microcontrollers and data acquisition systems.
The sensor supports a 0–100% RH measurement range and operates over a temperature range of −40°C to +80°C. An integrated heater provides multiple heating levels for applications where condensation or high humidity may affect measurements. The probe includes a breathable protective membrane, MRS connector, and 1-meter cable for remote sensing applications.
