    CS215 Temperature and Relative Humidity Probe Introduction The CS215 Temperature and Relative Humidity Probe is designed for general meteorological and other data logging applications. It uses the SDI-12 communications protocol to communicate with any SDI-12 recorder, simplifying installation and programming.

  • Page 12: Quickstart

    CS215 Temperature and Relative Humidity Probe Quickstart Short Cut is an easy way to program your datalogger to measure the CS215 sensor and assign datalogger wiring terminals. Use the following procedure to get started. 1. Install Short Cut by clicking on the install file icon. Get the install file from either www.campbellsci.com, the ResourceDVD, or find it in...

  • Page 14: Overview

    Overview The CS215 probe uses a single chip element that incorporates both a temperature and an RH sensor. Each element is individually calibrated with the calibration corrections stored on the chip. The element is easily changed in the field.

  • Page 17: Crbasic Programming

    The SDI12Recorder() measurement instruction programs CRBasic dataloggers (CR200(X)-, and CR800-series, CR1000, CR3000, and CR5000) to measure the CS215 sensor. This instruction sends a request to the sensor to make a measurement and then retrieves the measurement from the sensor. See Section 8.1, Sensor Measurements, for more information.

  • Page 18: Installation

    See Section 10, Attributions and References, for a list of references that discuss temperature and relative humidity sensors. When used in the field, the CS215 must be housed in a radiation shield. Typically, the 41303-5A six-plate solar radiation shield is used. The white color reflects solar radiation, and the louvered construction allows air to pass freely through, thereby keeping the probe at or near ambient temperature.

  • Page 21: Edlog Dataloggers

    8.1.1.2 Edlog Dataloggers The aM! command takes about 700 milliseconds in total to make a measurement from the CS215. If it is included in the main program table (table 1) the program will be delayed for this interval which will limit the maximum scan rate for fast running programs.

  • Page 22: Power Conservation

    CS215 Temperature and Relative Humidity Probe 8.1.3 Power Conservation The CS215 draws less than 70 µA of current between measurements. In most applications, this is insignificant compared to the datalogger and other power uses, so the sensor can be permanently connected.

  • Page 23: Maintenance

    CS215 Temperature and Relative Humidity Probe Maintenance The CS215 probe requires minimal maintenance. Check the radiation shield monthly to make sure it is free from dust and • debris. • Clear the white filter on the end of the sensor of debris. If dirt or salt is engrained into the filter, it should be cleaned with distilled water or replaced.
