Temperature and humidity sensor

The RS485 output mode can directly read the data through the 485 software, or connect the network collector to view the data remotely through the cloud platform. The analog output can be connected to PLC or other collectors owned by the customer to view the data.

This temperature and humidity sensor has two installation methods:

Wall mount
There is a slide rail mounting plate on the back of the transmitter, remove the mounting plate first. There are two expansion plugs and two self-tapping screws in the accessories. First, punch two holes with a diameter of 5mm and a depth of ≥30mm on the wall (the hole spacing is 70mm). After inserting the expansion plug, fix the slide rail mounting plate on the wall with self-tapping screws, and finally, slide it into the transmitter.

Slide rail installation
The back of the sensor is equipped with a slide rail mounting plate, remove the mounting plate first. The transmitter slides directly into a standard 35 rail.

Different sensors have the following errors according to the model of temperature and humidity sensor:
In the environment of humidity (60%RH, 25℃), the error is ±2-3%RH
Under the environment of humidity of 25℃, the error is ±0.4-05℃

• Analog temperature and humidity sensor
  The digital integrated sensor is used as the probe and the digital processing circuit is used to convert the temperature and humidity in the environment into the corresponding standard analog signal, 4-20mA, 0-5V or 0-10V. Analog temperature and humidity sensors can simultaneously convert changes in temperature and humidity values into changes in current/voltage values.
• RS485 Temperature and Humidity Sensor
  The output signal type is RS485, which can reliably conduct distributed monitoring with the host computer system, and can communicate up to 2000 meters. The standard Modbus protocol supports secondary development.
• Network temperature and humidity sensor
  The network temperature and humidity sensor can collect temperature and humidity data and upload it to the server through Ethernet/WiFi/GPRS. Make full use of the established communication network to realize long-distance data collection and transmission, and realize centralized monitoring of temperature and humidity data.

• The built-in probe cannot see the sensor from the outside, so the appearance is naturally more generous and beautiful. The built-in probe has extremely low power consumption, and can also reduce the influence of external factors such as aging, vibration, and volatile chemical gases on the sensor to ensure its good stability. One-piece installation, suitable for measuring the entire ambient temperature.
• External probe refers to the temperature and humidity sensor outside the instrument body. The advantage of the external probe is that the measurement range will be wider than that of the built-in sensor, because the sensor is not together with the display and the circuit part. It is suitable for measuring relatively small spaces, such as drying boxes, constant temperature and humidity boxes, refrigerators, etc.
