IoT smart meter

Introduction:

At present, single-mode communication technologies such as power line carrier or wireless communication are widely used in China. This meter adopts advanced measuring chips, accurate measurement, digital calibration technology, modular design, low power consumption, high accuracy, stable performance, easy installation, and easy maintenance. In the era of the Internet of Things, the drawbacks of single-mode communication are obvious, such as unstable signals and poor penetration capabilities. So, the IoT smart meter launched by Yima has spawned more intelligent applications. For example, in schools, parks, office buildings, large shopping malls, professional markets, urban complexes, etc., it can be used for electricity collection and pre-sale electricity management.

(9) Environmental humidity:<85% RH, no condensation;

(10) Size: 160 * 112 * 58 (without carrier module).

Advantages of IoT smart meter functions:

1、 Connect without bottom line

The biggest technology of NB IoT meters is their ability to support massive connections, low latency sensitivity, ultra-low device costs, low device power consumption, and optimized network architecture.

2、 Long battery life

As we all know, remote meter reading now requires batteries from smart meters to supply, and NB meters are no exception. However, they can increase battery life to at least 10 years and provide comprehensive indoor cellular data connection coverage.

3、 Low investment funds

Many people have used wireless meters in the past, and they all needed us to pull a network cable ourselves, buy a collector, and build a network to achieve remote meter reading and water and electricity management. However, now NB IoT meters communicate directly with the operator base station, without the need to build a relay network like LoRa protocol; Secondly, the RF and antenna of the operator's base station are basically multiplexed, without the need for complex hardware upgrades, which greatly reduces the cost of investment.
