Talk2 Whisper node CR2302 Battery Test
I’m currently testing batterylife with the whisper node and a CR2302 battery.
Talk2 Whisper node & ESP8266 base station code
I have my basic whisper code ready and working, I used part of the talk2 library code from their bitbucket repository and changed it to my needs.
ESP8266 Software
For my sensor project I want the ESP8266 and The HC-SR04 Ultrasonic sensor to periodically collect and send data to my server. For easy configuration of the esp I took the ESPwebconfig software and stripped it to the essential parts that I needed.
ESP8266 HC-SR04 PCB Version
By now I already have had a professional make the pcb design called vortexe9000 on fiverr, we discussed the design, I asked him to add a switch (pin 15 to gnd for easy flashing of the ESP) and he gave me some great advice to make it more compact (not needing the I2C and stepdown module).
Test Setup ESP2866 ESP-12 HC-SR04 on Batteries
I’m currently building a sensor based project, where a sensor needs to gather data every hour, and send it to a server, I first thought it would make sense to use an arduino board, connect a wifi shield and set the thing up.
