Receive sensor data or control devices via radio link!

Equipped with an ATtiny 84 microcontroller and an RFM12B radio module, the arpsensorsRF are capable of transmitting or receiving radio links. It has 6 inputs / outputs of which 5 can be used as analog inputs and one can be a dimmable output (PWM).

Like the arpschuino, it is able to control LEDs, low voltage lamps, motors, electromagnets, relays... Data from different analog sensors can also be processed and transmitted by radio.

The frequency used, 868MHz, is uncrowded, with antenna, the range can exceed 100m.

It can communicate with any other device equipped with an RFM12B radio module. It can be an arptefact::transceiver, an arpschuino² with an arpRF, a wilulu , a JeeLink classic or other arpsensors RF. Several sources codes are provided, You can choose wich one will be uploaded on your arpsensors RF.

Of course you can reprogram it via the ISP port (see this tuto).

There are 2 versions of the arpsensorsRF :

the classic version whose supply voltage must be between 2.8V and 3.6V. It can be equipped with a CR2032 battery holder. With such a battery, the autonomy in transmission of sensor data can reach 8h.

the regulator version whose supply voltage must be between 3.5V and 12V. This version is ideal for use with li-ion batteries, but also 9V batteries, 12v batteries ...

In addition, the regulator version can be optionally equipped with an IPEX connector for external antenna .

The arpsensorsRF kit is to assemble yourself. We can weld the RFM12B module or assemble the all kit on request.
