Lovely community here. So i got into the bandwagon of the superior ESP32. I am planning to build an entire data acquisition built around the ESP32. Would really appreciate it much if i were to get help from all of you. It would be a learning experience for all of us. So basically here are my project details and list of components being used.
A 32 Channel Data acquisition system with 30 sensors measuring strain (momentarily using a metal gage strain sensor of 120Ohm being fed to a quarter bridge circuit) and 2 temperature sensors(PT100). I would like an acquisition speed of atleast 1000Samples/Sec per channel. So here is my idea as of now.
32 Sensors connected to its each wheatstones bridge. The amplifier is done using the XR18910/XR10910, which is a 16:1 bridge Mux interface with selectable gain. I have attached link https://www.exar.com/content/document.a ... rt=XR10910
The XR18911 can be controlled via I2C link. it does all the amplification necessary. I will need to use 2 XR10910 or 4 XR18911(8:1 sensor interface). And then finally controlled by our LEGENDARY ESP32 which converts the analog data to digital. and with the help of wifi to transmit it to a computer where it can be collected in an excel file along with time of capture.
Could you guys kindly help me out on how i am to proceed with programming of the ESP32. I would really prefer to use Arduino IDE guys, as that seems to simplify things. Please let me know if you need more details. Thank you
