Yocto-PT100

Review(s): 6
Small device to measure the temperature with very high precision, using a PT100 temperature sensor (2, 3 or 4-wires supported). The device includes a built-in data logger to record measurements. The PT100 connection is electrically isolated from the USB bus. You can add Ethernet, Wireless or GSM connectivity to this device.

Description

Your own USB weather station: the Yocto-Meteo-V2 device will let you measure via USB the current humidity, pressure, and temperature, as well as record the pressure, ambient temperature and humidity on its internal flash for later retrieval when connected again by USB (built-in data logger). This product is ideal to build your own DIY weather station, and to monitor the weather conditions in your garden or the environmental conditions in your lab. 

This device replaces the original Yocto-Meteo, as the SHT25 sensor used in that first version is now end-of-life. The Yocto-Meteo-V2 is 100% backward-compatible with the Yocto-Meteo. It simply provides significantly more accurate measurements. The sensors on the Yocto-Meteo-V2 are water-resistant, without need for a SF2 filter cap. 

This meter circuit has been designed so that the sensor itself can be moved further away from the USB connector by a few meters: simply split the board into two parts and solder a 4-wire cable on the designated pads.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.
