Product description
Package contents:
1 x Load cell 0-5KG
1 x HX711 24BIT Precision ADC Module on breakout board
10 x Breakaway header pins for HX711 connection
Everything you need to take accurate force measurements with and Arduino, Raspberry Pi, or other microcontroller in one complete package!

Information:
Load cell - Sturdy aluminum alloy construction. Strain gauges pre-attached with strain relieved wires. Accurately measures forces from 0-5kg (0-11 lb).
HX711 - This top of the line load cell amplifier mounted on a breakout board pairs perfectly with the load cell to provide fast, accurate force measurements. It measures small changes in the resistance of the strain gauges mounted to the load cell and passes these values directly to any microcontroller (like an Arduino or Raspberry Pi).
Load cell specs:
-Wire leads pre-attached, 22 cm (8.5 in) long
-Dimensions 12.7 mm high, 12.7 mm wide, 80 mm long (0.5 in x 0.5 in x 3.15 in)
-4 mounting holes, 15 mm spacing on each side. One side both holes tapped M4 thread, the other side both holes tapped M5 thread.

HX711 specs:
-Operation Voltage: 2.7V–5V
-Operation Current: < 1.5mA
-Mounted on breakout board
-Includes breakaway headers for connection, soldering required

Technical Data:
TXD: serial transmit, 3.3V TTL level.
RXD: serial receiver, 3.3V TTL level.
CTS: serial flow control, is not supported.
RTS: serial flow control, is not supported.
DC: simulation, burning clock pin.
DD: simulation, data burning feet.
RST: reset pin module requires low level of not less than 5ms reset.
VCC: module power foot, requiring DC 3.3V power supply current is not less than 100mA.
GND: module common ground.
LED: LEDs module output pin, high output, series resistor connected LED.
Slave bright one second every two seconds. Once connected, LED lit.
KEY:. Input pin, internal pulldown This foot high, clear the record for the host address from the machine.
PIO: extended functionality for setting the module master-slave mode, the default internal pull-up resistor from the machine; external 1K pull-down resistor connected to ground, as the host. Currently only supports 9600bps communication, does not support the AT commands. Host, when pass-through traffic from the machine, there must be a certain time interval between packets. For example, the packet length is 500 bytes, then the transmission time interval between packets can be set to no less than 600ms. Otherwise, you may lose data.

This module uses the newest 2.4ghz transceiver from Nordic Semiconductor, the nrf24l01+. It integrates a complete 2.4ghz RF transceiver, RF synthesizer, and baseband logic including the Enhanced shockburst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. The ‘+’ version of the IC has improved range, sensitivity, and data rates. The command set is backward compatible with the original nrf24l01.Worldwide 2.4GHz ISM band operation 250kbps, 1Mbps and 2Mbps on air data rates Ultra low power operation Power supply : 1.9~3.6V Dimension : 12x18mm

5-18V power supply supported.- Serial USB TTL compatible for 2.85V, 3.3V and 5v signal- GSM, GPRS, GPS {text messaging, data transmission, positioning} triple function.
