my topic will seem a little strange, but here is the situation.
We are a community of 4000 members of whitewater sports and we want to have a tool for measuring the level of some rivers. Our knowledge in electronics is quite weak and would like to have your help to complete this project. We are looking for accurate and detailed answers from members who are familiar with the product. I have in the past created a similar project with the “Hologram dash” but I spent a crazy time completing it, which I would like to avoid this time. However it worked well, but would like to evolve towards the Particle product. The whole project will be very simple:
-Battery operated in remote location.
-The use of 3G and later Cat-M1 when available in Canada.
-An economical ultrasonic sensor (JSN-SR04T-rev2) and a 5v pressure transducer. (want to try both options).
-2 buttons for calibrating the measurement if necessary.
-1 measurement every hour
-Webhook to Thingspeak and possibly to website
-Watchdog Adafruit TPL5110 Low Power Breakout Timer
-Low cost and Simple design for noobies in order to make the project open source after field tests.
We are looking for help from a few members to participate in the development of the project, otherwise the project may not take place, which would be sad for the community.
thank you for your support and understanding.
