esp32, hx711, DS18B20 (temperature), relais, liquid sensor
Budget: €30 – €250 EUR
Hello together,
I want an esp32-microcontroller working over USB-powerbank, taking data from hx711 (loadcell), DS18B20 (Temperature-sensor) and a liquid-sensor.
The weight should be controlled every 10 Minutes. If there is a weight-loss of more than 1kg in 10 Minutes, send an Push-Message to my mobile.
Every second day there should be checked the liquid sensor and if there is no liquid in the tank, switch the relais (switches a pump) on for 60 seconds. The first day should be no relais switched.
Every hour there should be saved the data of temp, switch-time of the relais and the weight in the RTC-Memory. Every day at 2:00 p.m. should be read out the data and send it to a server in the internet. In the end the data should be in a MariaDB (mySQL)
Make an offer for the complete system. I have not much time for working together. Please calculate 20€ for hardware you should have, so you can deliver the code for a working and tested system.
What is it? It is a scale for a bee hive with feeding-system for young populations. They needed to be feeded one day and the next day they need time without sugarwater to make their work. The system should send the data at a defined time, so I have all the data when going to the bees and have only one data-package all the day.
Please send me also the price what you want for an hour additional work, when I want something edited....
