DC 4.5V-5.5V 51 Single-chip Ultrasonic Rangefinder Module 3CM-150CM LCD Display Temperature Alarm Distance DIY

''Product selling point
1: Wide range of applications
2: Simple to use
3: Wide measurement range, stable and easy to operate
4: Small and exquisite appearance
5: Measuring range: about 3CM-150CM

Parameter introduction:
Supply voltage: DC 4.5-5.5V;
Circuit board size: 8.2*7.6CM;
Measuring range: about 3CM-150CM;
Scattering angle: about 5 degrees;
Function description: To measure the distance of 3CM-150CM plane, an alarm distance can be set. When the measured distance is less than the set alarm distance, the relay will act. The LCD screen displays the measurement distance, the alarm distance, the current temperature, and the current speed of the sound wave.

Parts assembly steps;
When the measured distance is greater than the set alarm distance, the relay does not act, the normally closed and COM are connected, and the normally open and COM are disconnected. When the measured distance is less than the set alarm distance, the relay will act, normally closed and COM will be disconnected, and normally open and COM will be connected.
