I would like to create a temperature and humidity sensor based on the esp12f and the SHT31 chips alimented by 2 AA batteries. The components must ALL be on one side of the PCB but the PCB can have tracks on two sides. The PCB should not cover the esp12f antenna and the SHT31 should be placed far away from the antenna. The size of the PCB should be kept to a minimum. The cables of the battery holder are soldered by hand to the PCB. The deliverable are the PCB designs and the BOM in Gerber format and the associated source files. Here are the pin connections for the ESP12F: - GPIO16 should be connected to RESET. - EN/CH_PC pin should be pulled-up with a 10kOhm SMD resistor. - GPIO15 pin should be pulled-up with a 10kOhm SMD resistor. - There should be a tiny push-button connected between RESET and GND. Normally open. - There should be a tiny push-button connected between GPIO00 and GND. Normally open. - GPIO04 should be connected to the SDA pin of the SHT31 - GPIO05 should be connected to the SCL pin of the SHT31 - There should be connectors for the VCC, GND, TX, and RX pins. 22AWG wires will be plugged in. Here are the connections for the SHT31 - VDD/5 should be connected to the VCC - VSS/8 should be connected to the GND - There should be a 100nF SMD capacitor between the VDD/5 and VSS/8 pins. - The SDA/1 pin should be pulled-up with a 10kOhm SMD resistor. - The SCL/4 pin should be pulled-up with a 10kOhm SMD resistor. - The R/7 pin should be connected to GND. - The ADDR/2 pin should be connected to GND. - The ALERT/3 pin should be left floating. - The RESET/6 pin should be connected to VCC. - Die pad should be soldered and left floating. - The PCB around the SHT31D chip should be milled with a 1.0mm tool as illustrated in figure 10 b of the design guide. It should have round corners.

Hello. I'm Jose and you can see my work in the freelancer profile. First of all, I'll tell you, the price you want to carry out this project is too little, if someone does it to you for that reason, they will ask you for more. In short, my proposal would be to do everything you say and send the firmware code and guide for loading it on the arduino. If you are interested contact me and we can talk.
