Product Details

　　High precision wireless vibration sensorAll modules are designed with ultra-low power consumption, and the entire sensor node has very low current consumption. With two ordinary dry batteries, it can work for several years, greatly extending the maintenance cycle.

Thus, a micro vibration generator can also be used to collect the weak vibration energy generated by the structure using the piezoelectric principle, convert it into electricity, and provide power for the sensor. In order to reduce power consumption, ultra-low power products are selected for the sensor. The sensor is powered off or placed in sleep mode when not collecting data. The truly maintenance free research team has invented a sensor (wireless sensor) that can be implanted in the brain and emit wireless signals externally, which may provide a new tool for brain function research.

In the study, researchers invented a new type of sensor that can be directly implanted into the brains of large animals (pigs and rhesus monkeys), and can transmit the recorded brain signals to in vitro monitoring devices through wireless technology. Animals can move freely within a large range, and successful experiments have recorded data on their interactions with the surrounding environment. Wireless sensors can also be charged wirelessly to achieve long-term recording. The results show that the sensor can maintain stable signal transmission for one year

　　High precision wireless vibration sensorCharacteristics:

1. Transmission distance: Urban areas can reach 2-5 kilometers, while suburban areas can reach 15 kilometers.

2. Operating frequency: The ISM frequency band includes 433, 868, 915 MH, etc.

3. Standard: IEEE 802.15.4g.

4. Modulation method: Based on spread spectrum technology, a variant of linear modulation spread spectrum (CSS) with forward error correction (FEC) capability.

5. Capacity: A LoRa gateway can connect thousands of LoRa nodes.

6. Battery life: up to 10 years.

7. Security: AES128 encryption.

8. Transmission speed: several hundred to tens of Kbps, the lower the speed, the longer the transmission distance. This is similar to a person picking things, picking too many to go too far, and picking too few to go far.
