Environmental Sensing Platform
Battery-powered environmental monitoring system integrating custom hardware, embedded firmware, and wireless telemetry.
Overview
A compact, battery-powered platform for environmental data collection. Custom PCBs integrate temperature, humidity, and light sensors and transmit readings wirelessly via an ESP32 module.
Highlights
- Designed sensor + buck-converter PCBs in KiCad
- Integrated SHT40 temp/RH and VEML7700 light sensors over I²C
- Assembled SMT boards and debugged power + firmware interfaces
- Profiled system power using Joulescope
- Developed ESP32 telemetry firmware
Hardware Design
PCBs were designed from scratch in KiCad, incorporating a buck converter for efficient battery regulation and SMT footprints for the SHT40 and VEML7700 sensors. Joulescope power profiling guided deep-sleep tuning to maximize battery life between data uplinks.
