The 3.7 kB Alarm: A Zero-Bloat Edge AI Smoke Detector in Pure C You are building a critical IoT safety device — a smart smoke and fire detector. It monitors 12 environmental variables in parallel: temperature, humidity, TVOC, eCO2, raw hydrogen, ethanol, barometric pressure, and five particulate matter metrics. You want a neural network to catch the non-linear chemical signatures of an imminent fire before the flames start. Then you look at the industry standard for Edge AI. TensorFlow Lite for
