LoRaWAN Ex d Electro-chemical Gas Sensor (WSLRWEX-G) is designed with high sensitivity, high selectivity and a stable baseline that can detect gases even at low concentrations. The sensor can measure different types of gas such as CO, NO, NO₂, H₂S, NH₃, O₂, O₃, SO₂, Cl₂, HCHO... WSLRWEX-G meets Ex D standards, so it can be used in hazardous areas 1-21-2-22, and is commonly installed for applications such as Gas Leakage Detection, Ambient Air Quality Monitor, Indoor Air Quality Monitor. The sensor uses the LoRaWAN communication standard, which can connect and transmit data over kilometers to any LoRaWAN gateway on the market. The ultra-low-power design and smart firmware allow the sensor to operate for more than 5 years on just 1 battery with 15 minutes of updating.

What is the Principle of Wireless Charging? I. Electromagnetic Induction Both the charging base and the mobile device are equipped with internal coils. When they are brought close together, the transmitting coil generates an alternating current of a certain frequency, which, through electromagnetic induction, induces a current in the receiving coil of the mobile device. This process transfers electrical energy from the transmitting end to the receiving end, thereby initiating power supply from the charging base to the mobile device. Due to its simplicity, ease of manufacturing, and the support from companies such as Texas Instruments, Philips, Toshiba, Microsoft, Panasonic, Samsung, Sony, and Qualcomm, this method is the most prevalent in the market. However, wireless charging based on electromagnetic induction has its limitations, particularly the severely restricted transmission distance. II. Magnetic Resonance A magnetic resonator consists of a large inductive coil connected in parallel or series with a small capacitor. A matching resonance frequency is essential for energy transfer. For instance, when two coils serve as resonators, the transmitting end vibrates at a frequency of 10MHz, emitting an electromagnetic field. The receiving end must also vibrate at the same 10MHz frequency to receive the transferred energy. Compared to electromagnetic induction, wireless charging via magnetic resonance offers long transmission distances, efficient power supply, and the capability of one-to-many power transfer. However, since both ends must resonate at the same frequency, circuit frequency tuning is crucial yet challenging. III. Radio Waves This principle converts ambient electromagnetic waves into current, which is then transmitted through a circuit. This wireless charging method boasts a transmission distance exceeding 10 meters, making it suitable for long-distance, low-power charging and enabling automatic charging anytime, anywhere. However, due to low conversion efficiency, charging times are relatively long when using this method. IV. WiFi Wireless Charging This charging system primarily consists of two components: a Wi-Fi access point (router) and a customized charging sensor. Notably, this method does not require replacing traditional wireless routers; only software deployment and other solutions are needed. The charging function can coexist with internet access without mutual interference. Its advantage lies in allowing charging on-the-go, providing great convenience to users. However, it struggles with accurately locating charging objects and consumes significant power. V. Ultrasonic Wireless Charging This principle utilizes ultrasonic waves to transmit power over distances up to 15 feet (approximately 4.6 meters). With a dedicated wireless charging case, users can move around the house while their phones are charging.
