HX711

Based on Avia Semiconductor's patented technology, HX711 is a precision 24-bit analog- to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. HX711 is an ADC chip with preamplifier included. The chip is specifically designed for weight scales applications. The load cells which usually measure weight provide voltage outputs in millivolts. These outputs are difficult to handle directly by controllers, so we can use HX711 IC which takes these voltage signals and provide standard digital values which can be used by a microcontroller. The chip has integrated preamplifier specifically to handle these low voltages.

Digital Vacuum Regulator

“This is a Veneer Vacuum Press (Vacuum Pump) which has been modified with a Digital Vacuum Regulator to operate with a selectable vacuum pressure. This device is a replacement for the Vacuum Controller in my DIY Veneer Vacuum Press built …

Pinewood Derby Car Scale With Center-of-Gravity (CG) Calculation

“A key factor when building a pinewood derby car is its weight. The Boy Scouts of America and other organizations specify a weight of no more than 5 ounces. To improve performance many builders will add as much weight (mass …

DIY Arduino Smart Digital Scale | ESP8266 + HX711

“Hello to everyone, today I am here to show you a very insteresting project that I was working on for a while, it consists on a digital scale using the ESP-12S microcontroller plus a load cell and it HX711 …

Auto calibrate hx711 scale with known weight

“Scale smart solution I got a 4point load cell scale to sort out, and I thought it’s a good time to create a code that will allow me to calibrate it once and store that date in the eeprom …

DIY Arduino Precise 5 Kg Scale With Built-in Temperature Sensor and Automatic Calibration System

“The scale is a combination of science and engineering, the amount of mechanical pressure on the load cell produces some signals, the signal amplifies with HX711 and then it gets read by Arduino. for better reading, making the noiseless environment …
