Hello,

Has anyone tried to decode Paradox Spectra Security Systems serial interface? My plan is to get activity reports via Spectra's serial interface with JeeNode. I connected my JeeNode to Spretra's serial interface and successfully managed to transfer serial data packets to JeeLink. But I need to decode this serial communication... 

What differences are between RFM22-S1 and RFM22-S2? Only the crystal size?

edit: BTW did you manage to get it working?

Not yet. Waiting for RFM22 boards...

Hi Zitron,

Discover the secret - where do you manufacture the PCBs?

I want 
I've sent you PM.

google -> http://www.misenso.com/prototyping/dual-humiditytemperature-sht21-arduino/40/

This is for SHT21, I need for SHT21P.

do you have a datasheet link?

Hello,

Have someone found a library for temp/humi sensor SHT21P? It has PWM interface, not I2C.

For me it is not clear how you resolved this problem. Could you post your sample code, please?
