Hello Nahman,
I have 3+ years of experience in embedded domain. I have done many projects using Raspberry Pi, Arduino, ESP8266, ARM, AVR, Linux, GSM, GPRS, ZigBee, Bluetooth, RFID, WiFi. The scripting language I know are C, C++, python, Lua, NodeJS.
I will do this project with help of Yowsup on raspberry pi. After installation I will write a python script to send the temperature data to the whatsapp group.
Kindly start conversation to discuss.
It was nice to working with you last time. Hope you remember me.
Thanks and regards,
Chirag Jogi
