VELLEMAN Earth Listener Wooden Enclosure, VM211

measures the environmental values eCO2, TVOC, barometric pressure, temperature and humidity values detects lightning or electronic discharge that are up to 40 km away shows values on a 2.8-inch color touch screen implemented logging function on SD card (SD not included) special designed hardware with pre-programmed software for a plug-and-play, ready-to-use experience open source and fully Arduino based, easy to expand and modify stylish wooden enclosure (VM211) or special edition see-through plexi case (VM211SE) development board: microcontroller: ATmega2560 operating voltage: 5 VDC (USB) - power supply not included, 2m USB cable included free pins after build: 30 digital / 5 analog touch screen: TFT resolution: 320 x 240 TFT colour depth: 262 000 colour CCS811 sensor: Total Volatile Organic Compound (TVOC) sensing from 0 to 1,187 parts per billion eCO2 sensing from 400 to 8,192 parts per million I2C compatible interface BME280 sensor: temp range: -40°C to 85°C humidity range: 0-100% RH, =-3% from 20-80% pressure range: 30,000 Pa to 110,000 Pa, relative accuracy of 12 Pa, absolute accuracy of 100 Pa altitude range: 0 to 9.2 km (30.000 feet), relative accuracy of 1 m (3.3 feet) at sea level, 2 m (6.6) at 9,2 km (30.000 feet) I2C compatible interface dimensions (when assembled): length: 135 mm (5,31 inch) width: 41 mm (1,61 inch) height: 84 mm (3,31 inch) weight: 215 g enclosure material: laser cut wood (VM211) plexi enclosure (VM211SE) AS3935 sensor: distance estimation to the head of the storm from overhead to 40km in 15 steps detects both cloud-to-ground and cloud-to-cloud flashes SPI and I2C compatible interface The Earth Listener needs a burn-in time of 48 hours and at least 20 minutes of logging before the eCO² and TVOC values are stable. This experimental kit is for indicative purposes only. Values should be interpreted while considering the environmental situation. Keep your living space well ventilated.
