PA1204: Serial (RS-232) Temperature Humidity Atmospheric Pressure Light Sensor: Made in CANADA
The measured temperature is sent directly in °C or °F by a simple text protocol. The sensor sends the measured value according to a specific ASCII question-answer protocol.
The thermal sensor uses an element with an accuracy of ± 0.5°C for temperature measuring. A red LED indicates that temperature measuring is in progress.
