Indoor Temperature and Humidity Monitor

Indoor Temperature and Humidity Monitor Wall Mount LCD Display

Indoor Temperature and Humidity Monitor is used to monitor the temperature and humidity in a closed room for a long time and record the temperature and relative humidity.Principle of temperature and humidity detection: Digital temperature and humidity sensors are used, the thermal resistor and humidity-sensitive capacitor are packaged into a small chip, full-scale multi-segment calibration is used, and the calibration data is stored in the chip.

Temperature and humidity sensor: imported sht30

Product size: 122mm*102mm*36mm

LCD screen size: 76mm*53mm

Installation method: Wall-mounted hoist hole installation (spacing 77mm, rotation hole diameter 5mm) or hanging buckle installation (spacing 170mm)

Two power supply methods are available:

①. 10-30vdc wide voltage power supply, the power plug is suitable for the power plug and the output is 5.5mm*2.1mm*11mm or 5.5mm*2.5mm*11mm DC round hole plug.

②, 10-30vdc wide voltage power supply, terminal power supply

Long-term stability: temperature ≤0.1℃/y, humidity ≤1%RH/y

Response time: temperature ≤ 15s (wind speed 1m/s), humidity ≤ 4s (wind speed 1m/s)

Maximum power consumption: 0.4w

Wiring method: The terminal block adopts military-grade spring-type screw-free terminals, which can be connected by pressing and plugging in. You can quickly connect the wires even if there is no screwdriver on site. It can adapt to wire diameters of 0.3~2.0mm2.

Self-calibration: Temperature and humidity are calibrated and can be self-calibrated

RS485 configuration method: Device communication parameters can be modified through any one of buttons, configuration tools, and 485 commands.

Relay load capacity (optional): 24V DC 1A, hysteresis control can be set, associated with temperature and humidity alarm upper and lower limits.

Screen display: real-time value display of temperature and humidity, offline status prompt, temperature and humidity over-limit alarm prompt, RS485 address baud rate display, clock display. You can turn the page to view the upper and lower limits of temperature, upper and lower limits of humidity and other parameters.

Password protection: The device buttons are equipped with password protection function to prevent non-administrators from tampering with parameters.

Body alarm mode: built-in buzzer alarm, alarm sound: ≥80dB, the buzzer alarm can be turned off at any time by pressing the button
