This kit lets you build exactly that - a real-time embedded AI system that distinguishes a genuine cry from background chatter, TV sounds, or kitchen noise. You'll train a neural network to recognize baby cry audio, deploy it to an ESP32-S3, and create a portable parent alert unit. It's a complete machine learning project disguised as a parenting tool.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble two ESP32-S3 devices: a crib-side detector fitted with the INMP441 I2S microphone and a parent-side alert unit with a buzzer and red LED. The detector continuously captures audio, runs a TensorFlow Lite model trained by you on Edge Impulse, and wirelessly triggers the alert when a cry is detected. Both boards communicate over NRF24L01 modules, giving you a practical introduction to low-power wireless sensor networks.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eCollect and label audio data for baby cry vs. background noise\u003c\/li\u003e\n  \u003cli\u003eTrain a neural network classifier on Edge Impulse's online platform\u003c\/li\u003e\n  \u003cli\u003eDeploy the model to ESP32-S3 and run real-time inference on INMP441 audio\u003c\/li\u003e\n  \u003cli\u003eSet up wireless alerting between crib unit and parent unit using NRF24L01\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eESP32-S3 Dev Board\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eINMP441 I2S Mic\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eActive Buzzer\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e5mm Red LED\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eNRF24L01\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e100nF Capacitors\u003c\/td\u003e\n\u003ctd\u003e10\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e10�F Capacitors\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e10k?
