Details of the updated module information:
With address bits, network communication is possible.
Zero point calibration and weight calibration can be performed with one key, which is very convenient and the accuracy has been improved a lot
The sending part of the communication protocol is changed to 5 bytes, the address bit is added, the verification code is added, and the communication error rate is extremely low
Old module information details:
●AB dual-channel data acquisition, data transmission has active sending and passive sending; data types are divided into working mode 1 and working mode 2 for customers to choose to meet different user needs.
●Baud rate: 9600bps Check bit: No ?? Stop bit: 1 bit Total protocol length: 10 bytes
●Volume: length 3.3cm*width 2cm*height 0.3cm.
●Built-in single-chip microcomputer, controlled by N instructions such as peeling and calibration, easy to use. Save the underlying development time.
●The voltage regulator circuit in the HX711 chip can directly provide power to the external pressure sensor.
●Simple serial port TTL232 communication, which can be connected to a computer through a USB to TTL cable for data transmission, which is very convenient.
●It can simultaneously suppress 50Hz and 60Hz power interference.
●The power consumption is very small, and the typical working current is less than 5mA.
●Working voltage range: DC 4.7~5.5V.
●Working temperature range: -20 ℃ ~+85 ℃
