1、The Sensor Probe: Able to test both the temperature and humidity of the soil, this digital sensor probe also has a wide measurement range. 2、High in Accuracy: Adopting standard I2C serial interface, the soil sensor probe ensures high accuracy in the digital output, very reliable. 3、Wide Application: Widely used in machine room monitoring, warehouse, construction site, concrete test block detection, greenhouse and so on. 4、Has A Long Cable: Comes with a long cable of 3 meters, the temperature humidity sensor probe enables more flexibility in work and operation. 5、Quick to Install: Designed to have a light weight and a compact size as well, the I2C sensor probe is very convenient to install in minutes. 1 x Temperature Humidity Sensor Probe Item Type: Temperature Humidity Sensor ProbeModel: FS304-SHT35Working Current: < 10mAHumidity Accuracy: ± 1.5%RHTemperature Accuracy: ± 0.1℃Working Voltage: 3.3VTemperature Measurement Range: -20℃ ~ 100℃Humidity Measurement Range: 0- 100.0%RHCommunication Interface: I2CWorking Condition: -40℃ ~ 125℃, 0-99%RHStorage Condition: -20℃ ~ 80℃, 0~95%RHShell: IP67 waterproof 304 stainless steel housing. Line Length: Approx. 300cm / 118.11inOperating Condition: The sensor works normally within the recommended operating range, please refer to the picture. Long term exposure to condition outside the normal range, especially when humidity exceeds 80%, may cause temporary signal drift, drift +3%RH after 60 hours. After returning to normal operating condition, the sensor will slowly self recover to the calibration state. Prolonged use under abnormal condition can accelerate the aging of the product.
