Wall mounted temperature and humidity alarm

Instruction Manual

1、 Brief introduction:

Intelligent temperature and humidity alarm is a small temperature and humidity alarm that integrates data collection and control. Applied to the collection, detection, and monitoring of temperature and humidity sensor networks. The intelligent temperature and humidity controller is a temperature and humidity monitor specially developed for the fields of computer rooms, agriculture, forestry planting, and animal husbandry. This controller combines computer rooms, agriculture, and animal husbandry The characteristics of agriculture and forestry planting fields have adopted computer technology and advanced digital temperature sensor technology, overcoming the traditional analog temperature Sensors (such as thermistors, platinum resistors, etc.) have serious defects such as instability, large errors, susceptibility to interference, and the need for regular calibration. This instrument has stable measurement data, high accuracy, and strong anti-interference ability. It has broad application prospects in fields such as computer rooms, agricultural greenhouses, grain depots, forestry, and flower farming.

5、 Operating instructions

SET- Parameter setting key, used to store the new set value of the parameter and enter the next set parameter when in the setting state.

▲ - Set value increase key, used to increase the numerical value in the set state. In working mode, press this key to silence the buzzer.

▼ - Set value increase key, used to decrease the value when in the set state. In working mode, press this key to silence the buzzer.

The parameter settings are as follows:
