EnviroGo ESP32-S3 wearable environmental monitor features 7 sensors (Crowdfunding)

EnviroGo s 7 in 1 ESP32 wearable environmental monitor

EnviroGo is an ESP32-S3-based wearable environmental monitor that tracks Organic Compounds (VOCs), UV index, temperature, humidity, air pressure, light, and motion via a 9-axis MEMS sensor. It is designed for indoor and outdoor use, and can be worn, clipped to a bag, or magnetically mounted, making it suitable for homes, offices, travel, labs, and daily use where real-time environmental data is needed. EnviroGo supports built-in Wi-Fi and Bluetooth connectivity through the ESP32-S3 WiSoC, features a small 0.96-inch IPS display, a microSD card slot for local data logging, and an RTC for time-stamped records. The device samples data at configurable intervals, uses RGB LEDs and a buzzer for visual and audible alerts, and can process data locally with AI-based prediction to spot trends such as rising VOC levels or humidity changes (with a stated 7-day learning period). EnviroGo is designed for IoT developers, researchers, smart home users, and health-conscious individuals who […]

Witty Pi 5 HAT+ – A Raspberry Pi RP2350-based power scheduler with time, temperature, and voltage-based triggers

Designed by UUGear, the Witty Pi 5 HAT+ is a power scheduler board for Raspberry Pi that features an RP2350 MCU for running scheduling logic. It includes a high-precision RTC with voltage and temperature monitoring for automated power on/off, making it suitable for solar-powered projects, environmental monitors, and industrial controllers that require scheduled power on/off control to extend battery life. The board follows the Raspberry Pi HAT+ specification and accepts power from either a 6V–30V DC input through a terminal block or a 5V USB-C supply, while delivering up to 5A to the Raspberry Pi and connected peripherals. It can also work as a simple UPS, thanks to its dual “ideal diode” configuration with an automatic switchover feature in case of power failure. Other hardware features include an onboard DC/DC converter, an ID EEPROM for HAT+ identification, a CR2032 RTC battery, and a wide –30°C to +80°C operating temperature range. […]
