Hey guys, I am somewhat new to arduino here, and I had some questions regarding a project I am working on.
Firstly, the project description:
- 4x strain sensors with hx711 amplifier coupled to an arduino MCU transmitting recorded data wirelessly.
- Each of the 4 combos will be battery operated and attached to a spinning metal shaft of a moving vehicle.
- Data reporting is small being just one float value per node, but the reporting rate needs to be 10-80 times per second.
- 1x MCU receiving wireless data from all 4x sensor nodes. Data received will drive PWM outputs to the vehicle for an onboard gauge display.
I was gifted a handful of some Arduino Nano 33 Iot’s, and I was wondering if these little things can pull it off. I couldn’t figure out how to get 4x nodes to talk to one central unit wirelessly, nor could I find any decent examples of this over BLE or WiFi. I looked into mesh information for BLE and WiFi which the ESP chips seem capable of, but this board comes with a SAMD21 front end chip with the ESP32 chip crammed inside the U-Blox W102 module. This means we don’t have direct control of the ESP chip and any of its additional functions outside of the WiFiNINA library.
All examples and online material have only demonstrated how to control or send data over the internet to a smart device or wirelessly control the LED. Additionally, those examples found seem to focus on one device to another, not multiple devices fed into one central device.
So what’s the best method here? Is it even possible with this board? If so, please enlighten me.
As a bench test goal right now, I want to aim to utilize the onboard gyroscope readings of 4 boards to be simultaneously sent wirelessly to a central board with no outside devices involved (no computers, smart devices, routers). So what are your thoughts? Can this be done?
