Re: Combined Digital Temperature & Humidity Sensor

["Dave McLaughlin" <dave@xxxxxxx>]

I have 2 of them. One is installed in the weather station and the other a
spare at the moment.

The are the Cooks Match size but still very small for what it is. Try
comparing just humidity alone sensors and you will see how small it is and
the fact that you get temperature too. They are very stable outputs.

They are easy to interface to, but make sure the supply is very clean and
stable otherwise the readings are very poor. Put a 0.1uF cap very close to
the device.

The interface is non-standard and almost close to I2C but not quite but
again, very easy to do yourself.

if the above don't work, try through

under New Products, Sensors, SHT7X

2% RH, 0.5 C accuracy, two-wire digital interface.  And the size of a
matchstick (though the text doesn't say whether it's a Cooks Match or a
Pocket Match...)
