Offroad: XBee Coordinator API + Arduino UNO + RTC +Temperature Sensor + LCD-Display AND Remote XBee (Sleep Mode with low power consumption) + Temperature Sensor - PART I

What a long headline you might think - but this actually describes very well my longer absence to the blog.

I'm sorry to be again off-road to the book, but before starting with the last Connect-Port experiment in Chapter 7 I still have some things on my to-do list that developed from the preceding chapters of the book.

With the knowledge of all the things learned until now I was eager to implement my first own little project to get a simple temperature sensor network (one outside/ one inside temperature) with a real time clock (RTC) and displaying everything on a LCD-display working.

Base Station (breadboard version)

It's consisiting of:


Base Station:

• XBee in Coordinator API mode
• connected to an Arduino UNO
• Temperature sensor connected to Arduino (AD22100)
• LCD-Display (16*2) connected to Arduino
• Real-Time-Clock (RTC DS1307) connected to Arduino 

 Remote Sensor:

Remote Sensor

• XBee End Device Sleep Mode
• TMP36 temperature sensor connected
• Voltage regulator MCP1700 (with very low quiescent current <2µA)
• running on three AA rechargeable batteries

Part II will be on describing the Base Station.
