JC-WH01 Air Temperature and Humidity Sensor
Digital air temperature and humidity sensor with an imported sensing element and full-range compensation. Multiple outputs: voltage, 4–20 mA, RS485 Modbus-RTU and SDI-12.
Product Overview
The JC-WH01 Air Temperature and Humidity Sensor is designed for measuring air temperature and relative humidity. It uses an imported digital temperature and humidity sensor, with calibration data stored in its internal memory. Digital linearization correction and full-range temperature and humidity compensation support accurate and stable measurements.
The sensor offers multiple output options, including voltage, 4–20 mA current, RS485 with Modbus-RTU, and SDI-12. Temperature measurement ranges include −30 to 70°C or 0 to 50°C as standard options, with other temperature ranges available on request.
Installation and Usage Notes
The sensor can be connected to data acquisition devices, data acquisition cards, and remote data acquisition modules with differential inputs. Install the sensor away from chemically corrosive environments. Keep the sensor and its cables away from high-voltage electricity and heat sources. Store the sensor in a dry, ventilated indoor environment at normal room temperature. Do not disassemble the sensor during use.
Warranty
One-year warranty from the date of shipment. Failures caused by product quality issues, excluding human-caused damage, are covered by free repair or replacement during the warranty period.
