Specification: Item Type: Temperature and Humidity Sensor Model: FS304-SHT20/FS304-SHT21/FS304-SHT25 (Optional) Working Current: <10mA Temperature Measurement Range: -20℃ ~ 100℃ Humidity Measurement Range: 0~100%RH Working Conditions: - 40℃ ~ 125℃, 0 ~ 99% RH Storage Conditions: - 20℃ ~ 80℃, 0 ~ 95% RH Shell: 304 stainless steel, IP67 waterproof Line Length: Approx. 150cm / 59.1in Weight: 61 g / 2.2 oz(approx.) Model SHT20 Humidity Accuracy (%RH)±3 Temperature Accuracy (℃)±0.3 Voltage (V)3.3 Package List: 1 x Temperature and Humidity Sensor 1 x Line Mark Precautions: 1. The temperature and humidity sensor should be installed in a place where the temperature is relatively stable and most representative of the measured ambient temperature and humidity. 2. Avoid installation in places where the temperature changes drastically. 3. Avoid installing dead corners where air does not flow. 4. Avoid using it in a salt spray environment. 5. Avoid use in corrosive gas environments. Working Conditions: The sensor has normal performance within the recommended operating range. Long-term exposure to conditions outside the normal range, especially at humidity >80%, may result in temporary signal drift (after 60 hours drift +3% RH). When returning to normal After the working conditions, the sensor will slowly return to the calibration state. Prolonged use under abnormal conditions will accelerate the aging of the product. Storage Conditions and Operating Instructions: Humidity sensors are not ordinary electronic components and require careful protection. This must be taken seriously by users. Prolonged exposure to high concentrations of chemical vapor will cause the sensor reading to drift. Package List
