IMPORTANT NOTE:
Connection should be made via PCB sockets only. Soldering to the pins will seriously damage your sensor.
All performance data is based on conditions at 20°C, 50%RH and 1013mBar, using City Technology recommended circuitry. For sensor performance data under other conditions, refer to the Characterisation Note and Operating Principles.
