The Load Cell / Wheatstone Amplifier Shield (2ch) is intended for precise amplification of measurements specifically for bridge amplifiers, medical instrumentation and industrial process control. Instrumentation signals (for example from Wheatstone bridge sensors) are often in the order of mV (millivolts) or less, and need to be amplified for processing via ADC. This shield will allow you to interface two bridge sensors like load cells directly on your Arduino board. Fully assembled.

Just what I needed

This is just what I needed. The flexibility of tuning the gain with resistors is very useful. It is a better board as compare to HX711 in my opinion. Totally recommended.

Great learning experience

Simple straight forward board based on basic principles of resistance measurements (load cells, wheatstone bridges). Excellent to use as a building block to generate measurements to be use by other interfaces/systems.

Great Product

Fast shipping. Easy to setup and Arduino Code was straightforward. Extremely pleased overall.

Strain Gauge

Excellent shield!!! Works great gathering my mechanical data.

Best option on the market

I've looked for a load cell amplifier and this one has stood out among all other options. Sparkfun sells a single channel amplifier, but it only goes to 80 Hz by cutting a trace. However, the sparkfun one is digital and gives better resolution (24 bit, though much lower due to noise in a realistic application) than an arduino in its default configuration (12 bit). However, this one by default has a 100 Hz filter and is only limited by the ADC rate of the arduino, which should be able to just about keep up with 1000 Hz. For my application, I need high frequency measurements, and the arduino ADC resolution is adequate (12 bits), so this one is better for me hands down.
