hmm series – miniature digital -大富豪官方网站
the hmm series provides our smallest thermopile sensor chip and asic with digital output in a tiny to-46 metal housing for non-contact temperature measurements. it features a digital temperature output or voltage readout in a smbus compatible operation with an output range from -5°c to 115°c. in pulse width modulated (pwm) output mode, a desired output temperature range can be defined with respect to the desired temperature resolution. the sensor provides high accuracy over a wide temperature range with a resolution better than 0.1°c. this sensor is available as an “m-type” with integrated lens (l3.0) which provides a 4:1 distance-to-spot-ratio in comparison to the standard “j-type”.
