The Smart Science IoT Kit is where micro:bit projects stop being local and start producing data students can argue about. Sensors measure the room; the onboard Wi-Fi board sends those readings to a cloud service; students graph a week of results and work out what the numbers actually show. What's included: IoT:bit breakout board with an ESP12F Wi-Fi module, real-time clock and buzzer BME280 pressure, temperature and humidity sensor OLED display, PIR motion sensor, light sensor and noise sensor Soil moisture, water level and dust sensors, plus a sonar:bit ultrasonic sensor 180° servo, micro USB cable and connecting leads micro:bit board and lithium battery are not included — add a micro:bit V2 at checkout What students practise: Collecting real measurements over time instead of one-off readings Reading a graph they produced themselves and explaining the shape of it Connecting a device to a cloud service and understanding what "IoT" means concretely Block coding in MakeCode, with certified extension packages already available The kit works with ThingSpeak and IFTTT, so a class can set a threshold and have an email arrive when a reading crosses it. Sammat's Online Academy adds seven self-paced lessons for this kit, from cloud data logging to air quality monitoring and automatic irrigation — sold as an add-on, and included in the classroom pack.
