## Description

The STS35 temperature sensor from Sensirion gives a fully calibrated, linearized, and supply-voltage-compensated digital output and has an outstanding accuracy of up to +/–0.1°C. It provides an operating temperature range of -40~125°C and up to 1MHz I2C communication rate. Besides, the sensor can heat up itself to dehumidify the chip, which means it can function properly in a certain level of humidity. Pinout I2C Wiring Diagram Features Factory calibrated, accurate digital output High accuracy, ±0.1°C temperature error Fast startup time, 0.5msHigh reliability, long-term stability Applications Grain bin temperature monitoring Precise temperature controlling in LabAmbient temperature detection in greenhouseTemperature measuring in the environment with changeable humidity Specification Operating Voltage: 2.15~5.5V DCHeating Power Consumption: 3.6~33mWOutput Signal: I2CMeasuring Range: -40~125°CAccuracy: ±0.1°CResolution: 0.01°CPreheat: ≤1.5ms (Typical, 0.5ms)Response Time: >2sOperating Temperature: -40~125°CSize: 20x17.5x2mm/0.79x0.69x0.08”Mounting Hole Size: M2(2mm); Pitch 15mm Documents Product wikiSchematicsDimensions & Components Layout Shipping List Fermion: STS35 High Accuracy Digital Temperature Sensor x1
