Thermopile infrared sensor chip

The company's thermopile infrared sensor is a sensor based on the Seebeck effect principle. The sensitive components inside the device are composed of multiple sets of thermocouple pairs connected in series with each other. When the sensor receives the external infrared radiation, the temperature difference between the hot and cold ends of the thermocouple will be formed, resulting in a voltage signal to reflect the temperature value. The thermopile infrared sensor is composed of a thermopile MEMS chip, a 5-14um infrared band-pass filter, an NTC thermistor, and a miniaturized TO46 tube-shell package, which can provide accurate voltage output related to external infrared radiation. Sensitive core thermopile infrared sensor can be used in non-contact temperature measurement (forehead temperature gun, ear temperature gun), household appliances intelligent temperature sensing and control, air conditioning system field

Electronic cigarette pressure sensor

Electronic cigarettes do not contain tar and suspended particles and other harmful ingredients, with the improvement of people's health awareness, smoking electronic cigarettes is becoming a trend. In addition, the cigarette oil of the electronic cigarette can be flavored by adding flavoring agents of different components, and the user can select the taste of the cigarette oil according to his/her own preference.

MEMS Flow Sensor-MSL01

The flow sensor is based on the principle of heat conduction. The sensor structure consists of a micro heat source located on the sensitive film, an upstream temperature sensor and a downstream temperature sensor symmetrical to the micro heat source, and an ambient temperature sensor located on the silicon substrate. When there is no fluid flow on the sensor surface, the temperature field around the micro heat source is symmetrically distributed, such as (a); When there is fluid flow on the sensor surface, the temperature field around the micro heat source is disturbed due to the cooling effect of the fluid on the micro heat source, and the upstream and downstream of the micro heat source are asymmetrically distributed, as shown in Figure (B), the greater the asymmetry of the temperature around the micro heat source. The flow rate of the fluid is obtained by the temperature difference between the upstream and downstream temperature sensors
