The Yocto-Humidity device will let you measure the humidity and temperature via a USB connection, as well as record the ambient humidity and temperature on its internal flash for later retrieval when connected again by USB. This circuit has been designed so that the sensor itself can be moved further away from the USB connecter by a dozen of meters: simply split the board into two parts and solder a 4-wire cable on the designated pads.

This product has been replaced by Yocto-Meteo, that features an additional barometric pressure sensor.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM.

USB cables and enclosures to be ordered separately.
