Gravity: Multifunctional Environmental Sensor Brand_Troika in chips there could beThis multifunctional environmental sensor comprises an SHTC3 temperature & humidity sensor, BMP280 barometric pressure sensor, VEML7700 ambient light sensor and a ML8511 UV sensor into one board and offers 5 kinds of environmental parameters. Professional sensor chips are selected for each kind of parameter measurement. The reasonable layout and heat conduction of main chips are carefully considered in the circuit design, which effectively guarantees
