Hi, We developed a firmware that today works on an open source ESP32 / Max31865 cards. We need to develop the gerber file and list of materials unifying the following components: Use the TP-100 sensor (3 wires) for temperature reading. Below the detail of the plates and components used: 1) MAX31865 PT100 / PT1000 RTD-to-Digital Converter Board Temperature Thermocouple Sensor Amplifier Module 3.3V / 5V 2) TTGO ESP32 WiFi bluetooth Module Development Board 3) press button (reset) 4) press button (config) 5) 2 x 47k resistor - Measure battery charge 6) 2 x 10k resistor (press buttons) 7) Blue led A) The connection between the components can be changed to improve the efficiency of the project. B) To measure the voltage of the batteries, two 47k resistors are used in parallel with the battery and the reading is done through an ESP32 ADC port, if there is a more efficient suggestion, we are open to implementing it. c) There is a magnetic sensor of the reed switch type, which upon opening wakes up the plate from deep sleep. d) There are two press buttons and 10k damping resistors, one to reset and one to enter config mode. e) Ideal would be terminals to connect the reed switch and PT100 sensor. f) There is a blue led to show the status. if you can perform this activity please inform us of the amount and deadline for execution. More details can be sent if there are any questions.
