Soldering to the pins will seriously damage your sensor and invalidate the warranty. - Specifications are valid at 20°C, 50% RH and 1013 m Bar, using City Technology remended circuitry. Performance characteristics outline the performance of sensors supplied within the first 3 months. Output signal can drift below the lower limit over time. Doc.
