Project Summary:

The Human Body Infrared Smoke Temperature Alarm System works under the DC 5v voltage and uses the DH11 Temperature Module to detect the room temperature. When the module detects the temperature is higher than the maximum, the buzzer alarms and the red LED lights. When the MQ2 Smoke Sensor detects the smoke concentrations which is beyond the maximum , the buzzer alarms and the yellow LED lights. When the Pyroelectric Infrared PIR Motion Sensor detects the human movement, the Buzzer alarms and the blue LED lights. This system is a simple Smoke Temperature Alarm System which can be made simple at low cost and it suitable for warehouse and factory and so on.

Full Project:

Functions:

1) When start up, the 1602 LCD Board displays the setting interface.

2) Use two keys to set the maximum and minimum temperature.

3) When the DH11 detects the temperature is lower than the maximum, the buzzer dose not alarm, the red led dose

not light.

4) When the DH11 detects the temperature is higher than the maximum, the buzzer alarms, the red LED lights.

5) When the MQ2 detects the smoke concentrations which is lower than the maximum, the buzzer does not alarm

while the yellow LED does not light.

6) When the MQ2 detects the smoke concentrations which is higher than the maximum, the buzzer alarms, and the

yellow LED lights.

8) When the Pyroelectric Infrared PIR Motion Sensor detects the human movement, the buzzer will alarm, the

LCD1602 board displays RT:Y.
