VELLEMAN Earth Listener Wooden Enclosure, VM211

$99.00
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.
