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 −10°C to +70°C. An integrated heater provides multiple heating levels for applications where condensation or high humidity may affect measurements.
The stainless-steel probe housing features ventilation holes that allow ambient air to reach the sensing element while providing mechanical protection. Its compact 6 mm × 50 mm probe construction and 1-meter PVC cable allow flexible remote installation in space-constrained and monitoring applications. An optional protective membrane is also available for applications requiring additional protection from dust and environmental contaminants.
