HX711 Load Cell Amplifier Module PCB

₹119.00 Rs. 100.85 + 18.15 GST

This is an Amplifier Module to read load cell signals from a micrococontroller. Simple and easy to use. Arduino/ESP32 and Raspberry Pi libraries are available for easy setup.

In stock. 1-7 Day Delivery in India.

Loadcells are used to measure weight. Load cells are avialble in different measurement ranges from 100gms to 1000kgs. You can use this module to read the load cell values from a micrcontroller like Arduino or ESP and also with the RaspberryPI. This module converts the millivolts from a load cell and lets users ready them through a digital interface.

HX711 HX-711 is designed for high-precision electronic scales designed for 24-bit A / D converter chip. Compared with the same type of other chip that integrates the peripheral circuits including power supply, on-chip clock oscillator and other required the same type of chip, high integration, fast response, strong anti-interference advantages.

Reducing the overall cost of the electronic scales and improve the overall performance and reliability. The chip with the rear end of the MCU chip interface and programming is very simple, all control signals from the pin driver, do not need to register the chip programming.

Input selector switch can be arbitrarily selected channel A or channel B, its internal programmable low noise amplifier is connected. Channel A programmable gain of 128 or 64, corresponding to the full amount of the differential input signal amplitude was ± 20mV or ± 40mV. Channel B, compared with a fixed gain of 32 for the system parameter detection. The chip can provide the power supply to provide power directly to the A external sensor and chip A / D converter, analog system board without additional power supply.

Chip clock oscillator does not require any external components. Automatic power-on reset function to simplify the initialization process boot. Two selectable differential inputs Rene-chip, low-noise programmable amplifier with selectable gain of 64 and 128 Rene-chip voltage regulator supplies power directly to the external sensor and on-chip A / D converter Rene-chip clock oscillator requires no external components, if necessary, use an external crystal or clock.
