Wicked Node Kit




$15.95 ea.

This ATTiny24-based 433MHz platform is a remote sensor base. Add up to 4 sensors (analog or digital), and configure the board's broadcast schedule!

Description [Hide]

If you're looking to do periodic, remote measurements, here's a kit for you! Tie up to 4 sensors to the ATTiny24's 10-bit ADC channels, and have them streamed back to a Wicked Receiver mounted on your Arduino-compatible.

You can schedule your transmissions with three options:

  1. Sensor values are transmitted hourly.
  2. Sensor value are transmitted every 10 minutes. Both these modes are suitable for environmental data (temperature, etc).
  3. Whenever an event is detected, it is transmitted. This is the most power efficient mode, ideal for collecting event based data.

As this is designed for low power battery operated application, the chip "sleeps" most of the time and only wakes up to transmit or when it detects an edge on its digital sensor. You're also able to assign a node ID that is received with the datastream, so you can link multiple remote stations to one base station and keep your data sorted.

It will transmit the number of edges it receives in the hour, up to 255, plus three analog values. Why counted edges? What if you're attaching a simple contact sensor to a door you want to clock how many times is opened? TaDaaah! Simple solution!

Range is up to 300' ideally, but more realistically about half that.

The device features a LP2950 low-drop out voltage regulator, that will ensure solid 5V operation with an overhead as low as 40mV. If you're really concerned about power-consumption, you might want to hack in a small switching power converter.

Full assembly instructions are available.
