I'm looking for someone to develop the circuit with a Hall Effect sensor (something like that) with Wi-Fi. This design will be used to check if the door of a safe is closed / open. Basically the circuit will be off to save battery, as soon as the state is changed, the circuit will be turned on. I intend to program the device, I have preference in ESP for Wifi connection, but I am open to suggestions. The design needs to work with batteries, or a rechargeable battery something like 18650 battery

Its a pretty straight forward and easy task, i can program you a esp script to detect motion and post data to someplace over the network (locally or over internet) and also use deepsleep so that power consumption is also very low. about 20 micro volts and during operation about 60 milli volts, i have built this in the past for my home automation system so if you want i can give you a demo of my system as well, feel free to check my profile or text me for more information.

Hi. interesting project. The option you have chosen from esp8266 is excellent for the use of wifi. To turn off the device while it is not being used, it can be programmed to enter sleep mode after a certain period of inactivity. The hall effect sensor is also a good option for this application. On the other hand, remember that if there is no communication interface with the device, the user and the password of the equipment will be only in the code of the esp8266 and can only be changed by modifying the code. For any question or comment please do not hesitate to contact me. regards Darwin pardo

I have done many innovative products in embedded systems. I have some patented products like power saving in air conditioners by stopping misuse and it saves up to 72% of electricity as per test results. Similarly i have developed home automation system, plant care system. So I am very confident that i can do this design.

A simple proximity sensor and an Atmega Controller will do the purpose.
