How many pieces do you need made? Do you need conformal coating, I would suggest it. It inexpensive compared to replacing the board due to weather/moisture damage. What is the means/sensor to use to measure the liquid level? How will the battery be charged and what about its capacity the price will hinge on this. Do you need it incased? Hopefully no need for IP65 requirement Finally what is the rouge estimate you have for the BoM cost for each unit or do you like a quote for it? I am interesting in Mfg. this product for you.

This project sounds like an excellent use of my familiarity with microcontrollers such as the STM32, and WiFi units like the ESP8266, and a firm grasp of the English language. For this I would probably angle for a microcontroller running Arduino. Now, developing, testing, debugging, and polishing a circuit like this is no small task and I hesitate for this amount, but the project sounds like a lot of fun, and I love the way it takes advantage of solenoids. The first steps for us would involve hammering out requirements for your project. I set a month as the timeline, but to be honest, a professional grade project of this caliber would take longer. However, I am eager, I have ambition, and I know what I'm doing. I look forward to hearing from you.

I have 4 years + experience with IOT and Arduino compatible projects and have work on various projects like - GPS controlled Train Monitoring and Mapping System using Arduino - Smart Home automation using Esp8266 and Arduino - Voice controlled Lights using Esp8266 and IFTTT. - gesture controlled lights using Arduino. - pinball machine using Arduino. - and many more. I have worked on Arduino compatible board like Arduino UNO, Nano, Mega, Esp8266 nodeMCU, ESP-01, ESP12F, ESP12E. I am currently working on Air conditioning monitoring system that can track various parameters of A.C and send it to a web server and control A.C. on the response of data given by the user. The project is a commercial-grade product and I have considered factors like product cost-minimizing, its final dimensions and custom enclosure for it. with all these experiences and work I will be best suitable for your project and will I also have experience with Solenoids and mobile and Web App designing which will be an added advantage for you. I assure you that I will complete your project in the best possible way and you will be completely satisfied with my work. regards Jenish
