BT-359A

(1)Overview

The BT359A weigh module is made of high-integration circuitry that converts weak weighing signals into standard digital signals and the uart interface to other central control units. It is a cost-effective product designed specifically for the weighing needs of smart home appliances.

(2) Technical specifications

Power: 2.4V~3.6V

Working temperature: -20 ~ 50 ° C

Maximum humidity: 90% R.H non-condensable

Work V consumption: about 10mw (including sensor)

PCB physical size: (length) 30mm* (width) 30mm* (height) 3mm

Zero adjustment range: -0.3 to 0.3 mV

Input range: -5mV to 5 mV

A/D conversion speed: 16/sec

Nonlinear: 0.01% F.S

Gain drift: 100PPM/°C

A/D resolution: 1/200000

Maximum measurement accuracy: 1/50000

Communication interface: uart interface, 3v TTL

(3) Working methods

Weighing operation:

After the power is turned on, the status indicator flashes and is automatically cleared to work normally. It is realized by command method to obtain the functions of current weight, calibration, and peeling.

Peeling operation:

The master sends a tare command to the weighing module, at which point the weighing module returns a zero value. When the tare weight is removed, the weighing module will return the tare value of the negative sign.

 

(4) Communication protocols and formats

Uart communication parameters: baud rate 9600, no parity, data bit 8, stop bit 1
