MAD Burster: Magnetic Anomaly Detector with Burst Transmitter
Hardware
MicroMag 3
- MicroMag 3-Axis Magnetometer: Low noise, large resolution magnetic field sensing, stable over a wide temperature range.
- MicroMag3 Data Sheet
- Wiring Example
- Power: < 500 µA at 3 VDC (typ), 5.25 VDC (max)
Arduino Pro Mini 168 - 3.3V/8MHz
- Arduino Pro Mini: an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language.
- Details at arduino.cc
- Power: 25 mA @ 3.3 VDC (est.)
nRF24L01+ Transceiver Module with Chip Antenna
- nRF24L01+ Transceiver Module with Chip Antenna operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature - very nice!
Ardweeny
- Solarbotics Ardweeny fits on the back of the included ATmega328, taking up no more valuable breadboard space than the microcontroller itself!
