Indoor Temperature and Humidity Monitor

Indoor Temperature and Humidity Monitor wall-mounted LCD display

Indoor Temperature and Humidity Monitor is used to monitor the temperature and humidity in the home, with high-precision monitoring data to ensure a comfortable and healthy living environment.The principle of temperature and humidity detection: Use digital temperature and humidity sensors to package the thermal resistor and humidity sensor into a small chip, use full-scale multi-stage 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, rotary hole diameter 5mm) or buckle installation (spacing 170mm)

Two power supply options:

①. 10-30vdc wide voltage power supply. The power plug is suitable for power plugs and can be adapted to the output of 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

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 wiring terminals are military-grade spring-free screw terminals, and can be connected by one pressure and one plug. Even if there is no screwdriver on site, the wire can be connected quickly, and can adapt to the wire diameter of 0.3~2.0mm2

Self-calibration: The temperature and humidity are present and can be self-calibrated.

RS485 configuration method: You can modify the device communication parameters through any one of the keys, configuration tools, and 485 commands.

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

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

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

Body alarm method: Built-in buzzer alarm, alarm sound: ≥80dB, buzzer alarm can be turned off at any time through the button
