MSN

MySensors Nodes

Hardware and software for MySensors.org IOT network. The MSN PCB can be used for different node types. The minimal assembly consists of a Mega328P microcontroller (as seen on many Arduinos), a RFM69CW rf module with 868 or 433 MHz and some little stuff for reverse protection and battery monitoring.

With different assembly options, this PCB can be used for:

• Temperature, humidity and pressure measurements (With BME280 assembled)
• Sensor above with additional light level (with extra BH1750 on the proto field)
• Cheap temperature measurement (With DS18B20 assembled on the small proto field)
• IR-reader for digital Power meter (with external IR Head connected to UART)
• Prototyping on Breadboards with soldered pin header

The PCB features also

• ISP pins are connected to the pin header for flashing the bootloader
• Arduino pro mini compatible pin header for connecting a UART-board
• Optional LED for example for active transmission
• Mounting holes for fitting in the “Strapubox 6090” case
• A snap off proto board, which fit under or on top of the MSN PCB.

V0.1

Software tested on breadboards. Hardware not tested, because the boards are still in production.

V1.0

TBD Software modified to run on MSN PCB. Different improvements, like other libraries for enable power savings of the sensors.
