Figure Lengend Snippet: Design, assembly, and deployment of MyVivarium RPi-IoT sensor system. a. Components of Pi-IoT sensor system include 1: Jumper wires (to extend reach) 2: SHT30 Temperature and humidity sensor with plastic shell casing 3: VL53L1X distance or time-of-flight sensor which can measure distance to a person (vivarium-worker) 4: VEML7700 illuminance sensor which can detect lights ON and OFF 5 and 6: STEMMA-QT connectors (for Raspberry Pi GPIO pins to sensors and between sensors) 7: Raspberry Pi 4B (2 GB) in a case with a cooling fan. b. Fritzing sketch of serial connections between I 2 C sensors and Raspberry Pi GPIO pins based on a validated sensor module build. Wire color designations are as follows – red: power (+ve), black: ground (-ve), yellow: SCL (serial clock), blue: SDA (serial data). Note that in a, the color of SDA (data) is white. c. Assembled sensor module deployed in our vivarium room. Sensors have been affixed to the lower part of the mouse cage transfer station. The Raspberry Pi has been placed in a corner of a mouse cage rack.
Article Snippet: For each of our sensor modules, we used a Raspberry Pi model 4B with 2 GB RAM (Adafruit Industries LLC, NY) with a 128 GB RAM running the 64-bit Raspberry Pi Bookworm OS ( https://www.raspberrypi.com/software/ ).
