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....

Hi there, I just read your posting. It sounds like you need an expert in microcontroller programming. I have a background in IoT and Microcontrollers Programming and have been doing this for three years. This is my new account but I am doing freelancing since past three years.. I had done 15 to 20 of good IoT projects in my college and during lockdown period; some of those are: 1. Smart Water Pump Controlling System. 2. Accident Detection System. 3. Home Automation. 4. Smart Pet Feeder. 5. Voice Controlled Humanoid. 6. Voice and Remote Control Robotic Car. 7. Smart Health Monitoring system with ECG sensor, Oximeter and Pulse rate sensor. I have enough experience in Microcontroller Programming and I will do my best in this project. I will also provide you Proteus simulation for testing the project if you require. Link of some of projects are - [login to view URL] I have some great ideas which will surely make this project more cool and creative. I think this enhances my chances of getting hired. Best regards, Tushar Gupta

@AnkitBansal22

Hello Clinet, I read your problem statement of using the load sensor and the temperature sensor, we need to make the system. I am fully capable of doing this project. I have sensors and esp32 with me. I can also use the sqlite db on esp32 so we can store the data in the local as well as in cloud. I have other ideas also. So please let me know about it! Have a good day!

Hello, I'm alperen. I am an electronics engineer. I did the project you mentioned for pets. I know how to use all the sensors you mentioned. I have developed dozens of cloud-based projects so far. I can share my portfolio with you. I can explain to you which electronic components you should use in this project, how to connect the sensors and the esp32 card. I can write the C code necessary for the hardware to work and send it to you. I would love to work with you. I wish you a good day.
