Does anyone know how I can communicate with this [1] humidity sensor? It uses I2C but I can’t find any address in the datasheet. [1] http://datasheet.octopart.com/HIH8120-021-001-Honeywell-datasheet-23707982.pdf Thanks, Robert

Hello Robert, That datasheet seems very brief and limited. While I haven’t used the sensor myself, I think the following document may give you better information. (Note this is for the HIH 6000 series) I2CCommunications.pdf 133.13 KB Hope this helps! Mohit

A while back, somebody pointed me to this, which I’ve used to debug I2C issues on a Spark: // -------------------------------------- // i2c_scanner // // http://playground.arduino.cc/Main/I2cScanner // // Version 1 // This program (or code that looks like it) // can be found in many places. /…

@dougal , that needs to be added to the code snippets @kennethlimcp set up for sure! [image] Spark Code-Snippets There’s an increasing number of people asking about the same code issues they are experiencing and the WEB IDE hasn’t been able to support this just yet. So @peekay123 was c…

@peekay123 , thanks for the ping! @dougal , thanks for the post! i have updated the Spark-Snippets :wink: github.com/kennethlimcp/Spark-Snippets/blob/master/Snippets/0006%20-%20I2C_scanner.ino

@peekay123 , Yeah, I thought about that, but just didn’t have time do to it when I was posting. @kennethlimcp , Thanks for adding it anyways :smile: It’s not my original code, as noted in the comments. So all I can claim credit for is bringing it to your attention.

@dougal, that needs to be added to the code snippets @kennethlimcp set up for sure!
