Indoor Temperature and Humidity Monitor

Indoor Temperature and Humidity Monitor Wall Mounted LCD Display

Temperature and humidity detection principle: Use digital temperature and humidity sensors, encapsulate the thermal resistor and humidity-sensitive capacitor into a small chip, use full-range multi-segment calibration, and store the calibration data 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, rotating hole diameter 5mm) or hanging buckle installation (spacing 170mm)

Two power supply options are available:

①, 10-30vdc wide voltage power supply, the power plug is suitable for both power plugs and can adapt to the output of 5.5mm*2.1mm*11mm or 5.5mm*2.5mm*11mmDC round hole plug.

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

Temperature accuracy: ±0.5℃ (25℃)

Humidity accuracy: ±3%RH (5%RH~95%RH, 25℃)

Temperature range: -40℃~+120℃, humidity range: 0%RH~99%RH 

Temperature display resolution: 0.1℃

Humidity display resolution: 0.1%RH

Temperature and humidity refresh time: 1S

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

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

Maximum power consumption: 0.4w

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

Self-calibration: temperature and humidity are checked and can be self-calibrated

RS485 configuration mode: You can modify the device communication parameters by pressing buttons, configuring tools, or 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 temperature and humidity value display, 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-management personnel 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
