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.\n\nVersion 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.\n\nIntegrated Sensors & Modules\n\n\nUV Sensor (ML8511) – UV-A/UV-B detection, 280–390 nm\n\nEnvironment Sensor (BME280) – Temperature (−40 to +85 °C, ±0.5 °C), humidity (0–100% RH, ±2% RH), atmospheric pressure (300–1100 hPa)\n\nAir Quality Sensor (CCS811) – CO₂ (400–8000 ppm), TVOC (0–1100 ppb)\n\nWaterproof Temperature Probe – −10 to +85 °C display range (±0.5 °C)\n\nTDS Water Quality Sensor – Total dissolved solids measurement (max 55 °C water)\n\nCapacitive Soil Moisture Sensor – 3.3–5.5 V, PH2.0 connector\n\nLight Sensor – Analogue output (0–1023)\n\nSound Sensor – Analogue output (0–1023)\n\nOLED Display – 0.96\", 128 × 64 pixels, blue, 60 fps\n\n4× RGB LEDs (WS2812) – Individually addressable\n\nPassive Buzzer – 9 mm\n\nMotor Driver – PWM, compatible with N20 and 130 gear motors\n\nWi-Fi IoT Card – 802.11 b/g/n, supports IFTTT, ThingSpeak, EasyIoT, SIoT\n\n\nSpecifications\n\n\nPower – Micro USB (5 V) or 3× AAA batteries (4.5 V)\n\nDigital Output Voltage – 3.3 V\n\nGPIO – I²C ×2, P0, P1, P2, P8, P12, P13, P14, P15, P16\n\nProgramming – MakeCode, Mind+\n\nDimensions – 196 × 110.6 mm\n\n\n\nNote: A micro:bit board is required and not included. When using the Wi-Fi IoT card, power via Micro USB for reliable operation — AAA batteries may not supply sufficient current.\n\n\nIdeal For\n\nClassroom environmental science experiments\nSTEAM education and weather stations\nIoT and data logging projects\nWater quality and soil moisture monitoring\n\n\nPackage Contents\n\n1× Environment Science Expansion Board V2.0\n1× Capacitive soil humidity sensor\n1× TDS water quality sensor probe\n1× Waterproof temperature sensor\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3475,"title":"Default Title","sku":"DF-MBT0034","price":190.93,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":34,"option1":"Default Title"}]}
