BS 04: Reading all basic sensors

This example shows how to get the value of next sensors: Temperature sensor MCP9700A connected to ANALOG6 pin, Light sensor (LDR) connected to ANALOG5 pin and Humidity sensor (808H5V6) connected to ANALOG7 pin.

Required Materials

1 x Waspmote 1 x Battery 1 x MiniUSB wire 1 x 808H5V6 sensor 1 x LDR (electronic adaptation needed) 1 x MCP9700A Temperature sensor

Notes

This example can be executed in Waspmote v12 and Waspmote v15
