5. Some of IoT Devices
Particle
Every product starts as a
prototype. Our hardware
development kits — the Photon
(Wi-Fi) and the Electron (2G/3G
cellular) — help you build your
first IoT prototype in minutes.
Write your firmware in our web
IDE, deploy it over the air, and
build your web and mobile apps
with ParticleJS and our Mobile
SDK.

12. Which on will you use?
 Consider:
 Price
 Specs needed
 Size
 Programming language
 Community support

13. This time, I choose..
 Low price ($4/ IDR 52K – 110K)
 based on ESP8266
 11 digital I/O, 1 analog input
 Micro USB connection
 Compatible with Arduino and NodeMCU
(MicroPython soon)
 25.6mm x 34.2mm size
WeMos D1 Mini

14. Let’s see how it works
 What we need:
 WeMos D1 Mini
 Relay module
 Lamp set
 AgnosThings Account
