Dieser Blog befasst sich eingehend mit der Frage „Wie viel Strom verbraucht ein Kohlenmonoxidmelder?“.?”. Zusätzlich, we will explain the factors contributed to different electricity consumption of CO detector. Energy saving tips of CM detectors are also available in the end of the text.
Factors Affecting Electricity Consumption of CM Detectors
Sensor Type
In daily life, there are two common types, electrochemical sensors and semiconductor sensors. The electrochemical sensor works on the principle of constant potential electrolysis. When CO enters the sensor, the oxidant and reducing agent react. This results in a change in the sensor output current signal, which is completely proportional to the CO concentration. Im Gegensatz, the semiconductor sensor identifies the concentration by the change in the properties of the gas sensor after contact with the gas. In clean air, oxygen on the surface of gas-sensitive elements will bind electrons, resulting in a state where electrons are difficult to flow. When CO comes, the oxygen on the surface disappears after reacting with CO. Dann, the electrons regain their freedom and flow smoothly, causing an electrical signal. Inevitably, differences in the working principle of the sensor will lead to differences in power consumption.
Built-in Electronic Communication Module
IoT sensors usually have different electronic communication modules, such as WiFi modules, BLE modules, Lora modules and Zigbee modules. Wi-Fi is a wireless local area network technology that provides high-speed network connections for devices to access the Internet and communicate with each other. The Wi-Fi module usually converts the serial port into an embedded module, which complies with the Wi-Fi wireless network communication standard. It contains built-in wireless network protocol IEEE802.11b/g/n protocol stack and TCP/IP protocol stack.
Bluetooth is a short-range wireless communication technology. It is mainly used for point-to-point communication between devices. It features low power consumption, low cost and easy integration into various devices.
LoRa, a low-power wireless communication technology, is ideal for long-distance communication between iot devices. It features strong anti-interference capability.
ZigBee is a wireless communication technology based on the advanced communication protocol of IEEE 802.15.4 standard. It has the characteristics of low power consumption, low cost, low data rate and short distance communication. daher, it is particularly suitable for the situation where can not rely on external power sources for long-time operation.
Functional Diversity
The more functions of the carbon monoxide sensor, the higher its energy consumption. We take sensors with voice announcements, automatic shutdown, auto sleep/on functions. They requires additional circuits and components to support these functions, so its energy consumption will be higher than those of a single-function sensor.
Power Supply Mode
The power supply mode of the sensor is also an important factor affecting its power consumption. The energy consumption of sensors powered by DC power is relatively stable, but may be affected by the voltage and current of the power supply.
Working Mode
The operating mode of the sensor affects its power consumption. In wake mode, the sensor has to work continuously to detect carbon monoxide gas, so its energy consumption is relatively high. In sleep mode, the sensor turns off some or all of its functions to save power.
External Environment
External environmental factors may have an impact on the sensor’s power consumption. Zum Beispiel, temperature and humidity may affect the sensor’s internal circuitry and chemical reaction rate, thus affecting its energy consumption.

How to Pick out Low-consumption CM Detector
daher, it should be considered how to pick out a energy-saving sensor.
- Whether auto sleep/on functions are available to automatically reduce energy consumption when detection is not required.
- Whether it contain power-saving communication methods, such as BLE, Zigbee, Lora.
- Whether it has energy-saving sensing technology, like optical sensor, thermal conductivity sensor, and electrochemical sensor.
How Does Low-consumption CM Detector Save Electricity?
Sleep MOde
When the sensor detects that the indoors concentration of carbon monoxide is within a safe range in long run, it will automatically switch to sleep mode. In sleep mode, most of the sensor’s functions are turned off so the power consumption is reduced. On the contrary, when the carbon monoxide concentration exceeds the preset safe range, it automatically starts to work normally and detects the carbon monoxide concentration. This mechanism not only ensures that the sensor can respond quickly when needed, but also maintains a low power state when not needed.
BLE Communication Technology
After BLE radio module finishes telecommunication task, it will disconnect for entering a low-power state. This discontinuous connection significantly reduces energy consumption. Zusätzlich, BLE packets are much smaller than traditional telecommunication packets, so it reduces the power consumption of the computation when encoding and decoding.
Optical Sensing Principle
This kind of sensor usually adopts non-contact detection mode. Mit anderen Worten, they do not have to physical contact to detect the gas. Compared to sensors that require moving parts or gas sampling, this reduces the energy consumption to support mechanical motion. Zusätzlich, non-contact inspection avoids maintenance costs and energy loss due to mechanical wear.
How to Save Electricity Consumption When We Use CO Detector?
When installing a smart carbon monoxide sensor, we should choose right location to ensure that it can accurately detect changes in key corners.Beside, it is advisable to clean the sensor surface regularly to ensure its easy detection of carbon monoxide concentrations. If the sensor surface is contaminated, , it will consume unnecessary power. More and more, we can properly set the sensor alarm threshold to avoid energy waste due to mis-alert. Last, we are supposed to ensure right temperature and humidity surrounding the sensor. Otherwise, it will lead to degradation of sensor performance and more power consumption.
