Overview

All sensors are integrated into a single, small form-factor unit, requiring minimal installation effort. With a robust, no-moving-parts design that prevents errors because of wear, the ClimaVue 50 is ideal for long-term, remote installations.

Upon power up, the ClimaVue 50 initializes an internal timer to 55. This internal timer is incremented by 1 every second and resets to 0 after incrementing to 59. In addition, issuing an averaging command (M!, R0!, R3!, R7!, and C!) resets this timer to 55.

While powered up, the ClimaVue 50 takes solar radiation, precipitation, wind, and air temperature measurements every 10 seconds at internal time intervals of 0, 10, 20, 30, 40, and 50 seconds, then logs the values internally. By default, tilt, atmospheric pressure, relative humidity, and the temperature of the RH sensor are measured every 60 seconds at the internal timer interval of 4 seconds, and logged internally. Vapor pressure is computed from the relative humidity and air temperature every 60 seconds and logged internally.

The R7! command will force the instantaneous return of all the previous parameters, but must be used at intervals of 10 seconds or greater. When R7! is executed at a 10-second rate, the sensor returns samples. When the R7! or other SDI-12 measurement commands are issued slower than two times their default measurement interval, the sensor returns averages, accumulations, or maximums of the values it logged internally. It then resets its internal averaging counters and accumulators. Hence, oversampling is not necessary. Less frequent sampling decreases power consumption. For example, 10 seconds polling frequency requires 1 mA current compared to 0.4 mA at the recommended polling frequency of 60 seconds. The ClimaVue 50 has two error codes available—general error code –9999 and invalid wind measurement error code –9990.

Features:
