Temperature and Humidity Data Loggers

Temperature and Humidity Data Loggers are industrial wall-mounted high-protection casings, with IP65 protection, rain and snowproof and good breathability. The circuit uses imported industrial-grade microprocessor chips from the United States and imported high-precision temperature and humidity sensors to ensure excellent product reliability, high accuracy and interchangeability. The output signal type is RS485, and it can communicate up to 2000 meters. It is a standard modbus protocol and supports secondary development.
