Tuino 1 Simple Temperature Sensor

This simple IoT demo application delivers a temperature sensor. In this example we are using the LoRaWAN GMX-LR1 module for the Tuino 1. For a full description of the Tuino 1 check it's GitHub page TUINO 1.

You can use the kit with any LoRaWAN server, or use our Tuino Cloud platform, which uses Swisscom LPN or ThingPark by Actility connectivity.

Connecting the Sensors/Actuators

The Tuino 1 has 4 Grooove connectors:

• 1 Analog - A0
• 2 Digital - D4 and D5
• 1 I2C

Connect the sensors in the following order to make everything work out of the box

• Temperature on A0
• OLED Display on the I2C port

You can connect also the NFC antenna and with an NFC enabled smartphone you can read the temperature read by the sensor.

Payload Description

Here is a quick description of the payload we have implemented.

Uplink

 temperature_int = current_temperature * 100;

 tx_buf[0] = 0x02; // packet header - multiple data
 tx_buf[1] = (temperature_int & 0xff00 ) >> 8;
 tx_buf[2] = temperature_int & 0x00ff;

Easter Egg

Even if this is a simple temperature sensor, we have added a small 'easter egg'. Once you have uploaded the script you can go to the Tuino Cloud and send a Text Data to the node. And here you have your LoRaWAN pager!


Have fun and tweak the code and make other great stuff!
