Re: Interface with Sensirion EKH5 with Sensor SHT2x

Hi there, I already found where the problem was. Now I get the temperature without problem. At the end of the SHT2x datasheet it states that you can use the same protocol as in SHT7 so I did that based on this entry: http://forum.codemercs.com/viewtopic.php?f=1&t=1694 //sensor first time setup /...

Re: Interface with Sensirion EKH5 with Sensor SHT2x

Hi, thanks I tried that, but I always get following result back: 1st read: report[0] = 2 report[1] = 128 2nd read: report[0] = 3 report[1] = 128 and so on... (being the rest of the values 0). which does not seem to me any temperature reading... I have also tried to add the Read Temperature command H...

Interface with Sensirion EKH5 with Sensor SHT2x

Hi guys, I am communicating with the Sensirion EKH5 with Sensor SHT2x but I don't know what values I have to write in order to get the proper values of temperature and humidity from the sensor. These values from a SHT75 that I found in this forum: //Init I2C mode report[0] = 0x01; report[1] = 0x01; ...
