How to choose the right sensor device battery?
First, let we know what is the sensors device.
A brief introduction of sensors, the existence and development of sensors, so that objects have a sense of touch, taste and smell, so that objects slowly become alive. In modern industrial production, especially in the process of automatic production, various sensors are used to monitor and control various parameters in the production process so as to make the equipment work in a normal or optimal state, and make the products reach the best quality.
The main characteristics of the sensors device:
The new sensor has the trend of miniaturization, multifunction, digitalization, intelligentization, systematization and networking, it is also possible to build new industries that will become new sources of economic growth in the 21st century. Miniaturization is based on micro-electro-mechanical systems (MEMS) technology, which has been successfully applied to silicon devices as silicon pressure sensors.
The composition of the sensor:
The sensor is generally made up of four parts: the sensing element, the conversion element, the conversion circuit and the auxiliary power supply.
The sensor directly senses the measured physical signal and outputs the signal with definite relation to the measured physical signal The converter circuit is responsible for amplifying and modulating the electrical signal output by the converter. The function of intelligent sensor is put forward by simulating the coordinated action of human senses and brain, combining the research and practical experience of testing technology for a long time. Is a relatively independent intelligent unit, its appearance to the original hardware performance requirements have been eased, but by the help of software can make the sensor performance greatly improved.
The Sensor batteries:
1. Lithium thionyl chloride battery, Li-SOCL2 battery is a 3.6 V non-rechargeable lithium battery, with a wide operating temperature range, high energy ratio and longer discharge time features, widely used in a variety of sensors. Example: Tire Pressure Sensor Battery
2. The Lithium Manganese Dioxide (LiMnO2 battery) Battery has high and stable working voltage, high energy density, wide working temperature range -40 ° C to 85 ° C, low self-discharge rate and low storage self-discharge rate at room temperature 1%/year ; long life under 20 ° C 90% capacity after 10 years of storage
So, they have been widely used for all kinds of Sensor devices, RFID Reader, Personnel Positioning Card, GPS Tracker, Portable Listening Device, RFID Tag, LoRaWAN Devices, IoT, Animal Identification, Smart Card.
