HX711 Module Weighing Pressure Sensor 24 Bits

The resistance of the sensor has a force measurement range of 0-10 kg
Its resistance varies depending on how much pressure is applied to the detection area, the greater the force, the lower the resistance.
Peel and stick the rubber backing on the other side of the detection area to mount.
It can detect the applied force in the detection area in the range of 0g-10kg.
Circular force sensing resistor features:
- Detection area: 1.27cm / 0.5 inches
- Output signal: passive variable resistance
- Force detection range: 0 g ~ 10 kg
- Length: 6 cm / 2.36 inches
- Width: 1.9cm / 0.75 inches

The module uses a 24-bit high precision A / D conversion chip HX711.
The input circuit can be configured to provide a bridge.
The electric bridge voltage sensor model (such as pressure, weight) is an ideal sampling module with high precision and low cost. Module features: - Two selectable differential input channels
- Active low noise PGA with selectable gain of 32, 64 and 128
- Power supply regulator for load cell and ADC analog power supply
- Oscillator on chip that does not require external component with optional external glass
- Power-on-reset on the chip
- Simple serial control and serial interface: controls driven by pins, programming is not required
- Output data rate 10SPS or 80SPS selectable

- Low power consumption
- Input voltage: 2 - 5.5VDC
- Can replace the traditional touch of a button - Four M2 screws diameter 2.2 mm that position the holes for easy installation
- 3-pin control interface:
1- GND
2- VCC
3- Control signal (output pin)
- Power indicators: Bright green LED when the sensor is on
