DESCRIPTION

Mainly purpose of the BMS36T001 is to utilize a proximity sensor to detect whether an object has entered the detection range, and then control the motor.
For example, when applied to a touchless faucet, it detects if a person is standing in front of the sink, and if detected, controls the motor to dispense water.

The motor driver required an external power. Please follow the steps below to operate the power supply to prevent any damage.

Power on/off Sequence
1. Power up the BMS36T001.
2. Supply power and power up the motor driver
3. If you don't need to use the motor driver, shut down its power first.
4. Shut down BMS36T001’s power

HARDWARE OVERVIEW

PIN DESCRIPTION

You can insert the product into an Arduino UNO or the BMduino-UNO, BM53A367A, which is designed by Best Modules,. You don't need an external cable, just connect the shield to Arduino UNO or the BM53A367A.

Other pins are not used.

Pin name	BM53A367A pin	Function
INT	~D2	Object detected: output low Object non-detected: output high
RX	~D1	UART: RX
TX	~D0	UART: TX
GND	GND	Ground
RESET	RESET	Reset BM53A367A
IOREF	IOREF	Positive power (Power supply of BM53A367A: 3.3V)

You can use the BMCOM on the BMS36T001 to connect to the BM53A367A as well.

Pin	Pin name	Function
1	INT	Object detected: output low Object non-detected: output high

5	GND	Ground

HOW TO LEARN THE SENSING DISTANCE?

The BMS36T001’s sensing distance is 1 to 100cm, and it is configurable.
To change the infrared detection position, please refer to the below steps:

Connect the BMS36T001 to development board, such as Arduino UNO or BM53A367A.
Place something, such as a sheet of paper, above the infrared sensor of the BMS36T001.
For example, if you want to change the distance to 50cm, place something above the infrared sensor from a height of 50cm.
Press and release the Auto Calibrate button in 0.5 second, and the LED indicator starts shining slowly. The sensing distance learning started.
The LED indicator stop shining once the distance learning completed.
