DataNab LLC: Temperature and Humidity Sensors
September 19, 2011
Expanding the company’s range of one-wire temperature sensors, the new sensors — an inline potted digital temperature sensor, stainless steel digital temperature probe, and flush-mount room temperature sensor — provide additional low-cost options for temperature monitoring and control applications, says the company. They can be used in HVAC and refrigeration, as well as solar, geothermal, and other alternative energy systems that use multiple temperature sensors to monitor and track system performance. New sensors include an inline-potted design, a miniature stainless steel probe design that can be strapped to pipes, and a flush-mount room temperature design that can be concealed within walls. The company’s intelligent temperature and humidity sensors feature built-in, uniquely addressable chips to support communication over a single cable, minimizing costs associated with labor and materials. The built-in addressability of the one-wire chips allow the sensors to communicate to a central controller over a single-cable network in a daisy-chained fashion. This provides a more efficient alternative to legacy solutions that require a dedicated home-run cable to the controller from each sensor, eliminating the need for multiple wires and multiple A/D input connections.
