HX7is a precision 24-bit analog to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with . This Instructable describes how to make a small weighing scale using readily available off the shelf parts. Picture of HX7Library. Communicating with the Balance Module requires a driver for the HX7sensor. Arduino – this design uses a standard.
The simplest way to install the driver is to download the HX7library.
I am working on an application where i need to convert the weight of a person to calculate and use it for other parameter. So i started searching the internet and found many tutorials using the load cell and arduino. With the help of Visuino the task is so easy that you can complete.
Simple driver for the HX7ADC. Allows you to use the inexpensive HX7strain gauge amplifier and 24-bit ADC to build scales, force gauges . The HX7uses a digital serial protocol. Sparkfun has software that bit-bangs that protocol over any pair of IO pins you choose.
There is nothing special about which pins are chosen – any two can be used.
Most strain gauge will not come with a platform. Load Cell like 500g, 20kg or even 200kg. You will need to build one. A basic scale will look something as below.
Woo plastic or metal flatsheet should do the job. We have seen weight machines at many shops, where machine displays the weight just by placing any item on the weighing platform. So here we are building the same Weighing machine by using . In the standalone mode, the device can only indicate the measured forces on . It endeavors to provide the products that you want, offering the best bang for your buck. Whatever arduino hx7styles you want, can be easily bought here. The 25th pulse at PD_SCK input will pull DOUT pin back to high (Fig.2).
V both times with the popular library. GPIO-based implementation available. Je určen pro vysoce přesné měření analogového signálu.
