Integration is the signature of semiconductor technology. Microchip Technology’s RE46C190 3V photoelectric smoke-detector IC integrates a horn driver and boost regulator. In addition, the IC has programmable calibration and operating modes that can be selected and calibrated during manufacturing. This simplifies smoke-detector design and manufacturing. The integrated photoelectric smoke detector requires minimal external components. The […]

Revolutionizing the Design of Sensor Systems
Filter Protects Small Digital Humidity Sensor
It takes a variety of components to make a sensor appropriate for targeted applications and environments. To protect Sensirion’sSHT2x humidity and temperature sensor from water, dust, dirt and various contaminants, the SF2 filter cap is such a component. Made of PBT (Polybutylene Terephthalate) the filter cap has an integrated filter membrane. With a filtration efficiency […]
Endress+Hauser Introduces Four New Analytical Sensors
The new IP68-rated Memosens analytical sensors are “plug and play” compatible with the company’s recently announced Liquiline M CM442 four-wire, two-parameter transmitter. The Oxymax COS61D is an Optical Dissolved Oxygen sensor that uses the luminescence principle of fluorescence quenching. It has a measuring range of 0-20 mg/l (20 ppm). The Indumax CLS50D is a non-contacting […]
Four-wire, Two-parameter Transmitter Reduces Cost / Saves Space
Endress+Hauser’s Liquiline CM442 is a four-wire, two-parameter transmitter for analytical sensing applications. By accepting data from any two of the company’s Memosens sensors such as turbidity/suspended solids, nitrate, SAC (UV254), ISE, dissolved oxygen, pH/ORP, chlorine, concentration and conductivity, the transmitter avoids the cost of a second device and saves space with a simplified system. Powered […]
Humidity and Temperature Sensor Qualified to Automotive AEC-Q100 Requirements
Many environments require special qualification testing to prove that the product can withstand more than usual application requirements. This can include Underwriters Laboratories (UL), International Electrotechnical Commission (IEC) or in the case of automotive, the Automotive Electronics Council (AEC). Sensirion’s SHT21 humidity and temperature sensor has passed rigorous AEC Q100 qualification testing. The capacitive type […]
