eNVIRO is a weather station and clock with 7" touchscreen display with external solar powered unit unit for external temperature and humidity measurement.
Base unit (eNVIRO)
The base unit employs precision sensors that ensures accurate measurements of the environmental conditions. Through its huge 7" touchscreen display, it is possible to display the main environmental parameters as well as advanced parameter such as: dew point, heat index, absolute humidity, air density, and carbon dioxide concentration. In addition, the unit fits a RTC for precision time and date keeping. The 3D-printed housing has a simple and elegant design; the 3D files will be available here soon.
Preliminary hardware list:
SHT31 - Temperature and humidity sensor
MS5611 - Absolute pressure
DS3231 - Real time clock (not necessary if using eDOTcore board)
MH-Z19 - NDIR Carbon dioxide sensor
PMS5003 - Particulate matter 1, 2.5 and 10 sensor
ITEAD Nextion NX8048t070-11 - 7" Touchscreen display
eDOTcore or any Arduino board
External sensor (eNVIRO sense)
The external units employs the same temperature and humidity sensor of the base unit that ensure to have the same accuracy. The sensor is housed inside a Stevenson screen that provides the necessary shielding of the sensor, hence allowing accurate measurement of the environmental conditions. The unit is powered by a 3.7V 2000mAh Li-Po battery; a 6V 1W solar panel ensures the battery to be charged during the daytime assuring continuous operation.
