The OKY3066 is a 4-30V analog temperature sensor with atmospheric sensing capabilities manufactured by OKYSTAR. It is equipped with an IC LM35 integrated circuit for sensing precision temperature measurement. The sensor provides temperature readings between -55°C and 150°C with an accuracy of +-1°C and a response time of 0.125 seconds. It is suitable for a variety of applications such as measuring atmospheric temperature, controlling ventilation, detecting smoke, and other similar activities. The sensor is equipped with LED indicators for power status, corrected value, and alarm status. The sensor is also protected against overvoltage, reverse polarity, and short-circuit conditions.
