From Sensor Event to Human Alert: Designing a Reliable ESP32 Notification Pipeline

From Sensor Event to Human Alert, Designing a Reliable ESP32 Notification Pipeline

An ESP32 can read a sensor and send a message in a few lines of code. That is enough for a bench demo, but it is not enough for a reliable alerting system. The difference appears when the project runs unattended. Sensors bounce, readings hover around thresholds, Wi-Fi drops, and a fault can generate hundreds of repeated events. If every raw event becomes a notification, the engineer quickly learns to ignore the channel. A better design treats messaging as the last stage of an event pipeline: detect the condition, decide whether it matters, then notify a person. Start by Separating Detection From Notification Detection answers a machine question: did something change? Notification answers a human question: does someone need to know about it now? Those questions should not be handled by the ...

MAX30102 Sensor Library for Proteus V1.1 (Pulse Oximeter + Arduino)

MAX30102 Sensor Library for Proteus V1.1: two Arduino UNOs with purple GY-MAX30102 boards, the MAX30102 Advance pop-up Sensor page at REST 60 with 60 BPM, 98 % SpO2 and the PPG pulse wave, and the TEP Serial Monitor printing the pulse estimates

Hello friends, I hope you all are doing great. Today, I am going to share the new MAX30102 Sensor Library for Proteus V1.1 . The MAX30102 from Maxim (now Analog Devices) is a small pulse oximeter and heart-rate sensor , best known on the purple GY-MAX30102 breakout. With this MAX30102 Sensor Library for Proteus , you set the pulse rate, the SpO2 and the finger with presets and sliders, and your Arduino reads the red and infrared samples over I2C with the same SparkFun MAX3010x library you use on real hardware. Version 1.1 replaces the first version of this post. You now get two devices : MAX30102 Simple , with a control panel on the schematic, and MAX30102 Advance , with a pop-up window and four measured sensor test tools . The light is now a realistic pulse wave, and the new MAX30102 Ardu ...
