The SRH1A Humidity and Temperature Sensor is a highly accurate and cost effective probe with robust POM-C enclosure. It has been prepared for outdoor and indoor environments. Can be used with Wind2measure RADIO Data Logger or integrated with other manufacturers' equipment. INSTALLATION Thanks to its compact size and multiple mounting methods, the sensor fits into tight spaces and can be fixed to masts, walls and other constructions. SRH1A is suitable for installation with a radiation shield which protects the sensor against water, dust and direct solar radiation. Apart from standard 1m cable, other cable lengths are available. OUTPUT The sensor is equipped with an SDI-12 output and is compatible with all data loggers using this communication standard.SDI-12 (Serial Digital Interface at 1200 baud) is a serial communications protocol used in environmental measurements. The operating principle is that only an SDI-compatible device with the digital addressing system will communicate with a the pre-configured sensors. Unless the sensor has a matching configuration, it will not respond and stay in a sleep mode. SDI-12 sensors have a three wire connection. HOUSING The housing is made of POM - C, highly rigid material known for its hardness, durability, good creep resistance and low water absorption. As the material is fully ESD compliant, the sensor can be installed in Electrostatic Discharge Protected Areas (EPA). The cap holds the stainless steel filter with pores of 33 µm. Electronic components are sealed with epoxy resin. TECHNICAL INFO: HUMIDITY Measuring range 0 ... 100%RH Accuracy at 25 °C ±1,8%RH (0 ... 90%RH), ±3,0%RH (>90%RH) ±0,3°C (0 ... 60°C), TEMPERATURE Measuring range -40 ... +60°C Accuracy at 25 °C ±0,5°C (for the remaining range values)
