Beautiful work! You've inspired me.

Can you please upload a schematic of how you integrated the SN74LVC2G14DBVR, or explain in detail? I ordered these parts on Digikey hoping to get my project to work

I'm trying to run 2 of the STHS34PF80 on the AVR-IOT Cellular Mini and you're the first person I've seen clever enough to get around the stubborn unchangeable I2C address (0x5A) - I couldn't get the microcontroller to recognize SPI.

Also need to connect a KX132 accelerometer to detect tampering.

I'm struggling because it seems like I fix one issue, and another pops up. My application is very similar to yours, except it is using a cellular network and MQTT messenger app.

Hi Paul,

Thanks for the kind words. Those components should work. Perhaps the attached schematic snippet will help. I also have an accel and baro on the same I2C bus (SDA/SCL). A0 is a host GPIO used as a TTL toggle. D4/D5 are host GPIOs for the sensor interrupts, etc.

Let me know if I can provide anything else.

Kris
