LumiLog – A “Parasitic” PCB Light Logger for Packaging & Supply Chains 🌞🔋 Hello Techies ⚡ Imagine a tiny PCB (around 2.5 cm²) that quietly hides inside packaging, powered only by a coin cell, and still logs ambient light exposure for a week or more. That’s the idea behind LumiLog — a parasitic logger that: 🪶 Is so small it can ride along in shipping boxes, packages, or wearables. 🔋 Runs entirely off a single 220 mAh coin cell, no recharge needed(change the battery if its dead) 🌞 Uses a photodiode to detect light/dark transitions without wasting energy on continuous ADC scans. 🧠 Stores events in FRAM memory (virtually unlimited writes, survives power loss). 💤 Stays asleep >99% of the time, sipping nanoamps–microamps in standby. Why it matters 🚀 Supply chain monitoring → know if a sealed cold package was opened or exposed to sunlight. Cold chain logistics → track light exposure for temperature-sensitive goods. Sustainability → ultra-low-power design = longer life on tiny batteries. Bom Cost - around 10 dollars. The vision 🌟 This isn’t a “big IoT box with batteries.” It’s a parasitic sensor that you can just slip into packaging and forget. At the destination, you pull the data and instantly know the exposure history. 👉 It shows how much impact even the smallest embedded systems can have when optimized for ultra-low power + clever sensing. #PhotonLog #LowPowerDesign #IoT #Packaging #SupplyChain #EmbeddedSystems
