Express post shipping available (product has a short lead time)

The Environment Science Expansion Board V2.0 is a micro:bit add-on designed for STEAM education, integrating 14 environmental sensors and modules onto a single tree-shaped board. Students can measure UV levels, temperature, humidity, air pressure, air quality, water quality, soil moisture, sound, and light — covering the key aspects of nature and environmental science.

Version 2.0 adds a Wi-Fi IoT card for connecting to platforms like IFTTT, ThingSpeak, and EasyIoT, plus TVOC/CO₂ air quality sensing, 4× WS2812 RGB LEDs, a motor driver, and an improved OLED display. Program with MakeCode or Mind+ and power via Micro USB or 3× AAA batteries.

Integrated Sensors & Modules

  • UV Sensor (ML8511) – UV-A/UV-B detection, 280–390 nm
  • Environment Sensor (BME280) – Temperature (−40 to +85 °C, ±0.5 °C), humidity (0–100% RH, ±2% RH), atmospheric pressure (300–1100 hPa)
  • Air Quality Sensor (CCS811) – CO₂ (400–8000 ppm), TVOC (0–1100 ppb)
  • Waterproof Temperature Probe – −10 to +85 °C display range (±0.5 °C)
  • TDS Water Quality Sensor – Total dissolved solids measurement (max 55 °C water)
  • Capacitive Soil Moisture Sensor – 3.3–5.5 V, PH2.0 connector
  • Light Sensor – Analogue output (0–1023)
  • Sound Sensor – Analogue output (0–1023)
  • OLED Display – 0.96", 128 × 64 pixels, blue, 60 fps
  • 4× RGB LEDs (WS2812) – Individually addressable
  • Passive Buzzer – 9 mm
  • Motor Driver – PWM, compatible with N20 and 130 gear motors
  • Wi-Fi IoT Card – 802.11 b/g/n, supports IFTTT, ThingSpeak, EasyIoT, SIoT

Specifications

  • Power – Micro USB (5 V) or 3× AAA batteries (4.5 V)
  • Digital Output Voltage – 3.3 V
