Specifications:
Power Supply: 5V DC
Quiescent Current: < 2mA
Output signal: high 5V low 0V
Effectual Angle: < 15°
Ranging Distance: 2cm - 500 cm
Resolution: 0.3 cm
Mode of Connection: VCC / trig (T) / Echo(R) / GND
(VCC: supply 5V; GND: ground wire; TRIG: trigger control signal input; ECHO: echo signal output.)
The distance can be calculated with the following formula :
Distance L = 1/2 × T × C
Where L is the distance, T is the time between the emission and reception, and C is the sonic speed. (The value is multiplied by 1/2 because T is the time for go-and-return distance.)
Attention:
The module should be inserted in the circuit before power on, avoiding it works in a high level.
2. The module is not intended to connect directly to electric, if connected electric, the GND terminal should be connected to the module first, otherwise, it will affect the normal work of the module.
3. When tested objects, the range of area is not less than 0.5 square meters and the plane requests as smooth as possible, otherwise, it will affect the results of measuring.
