Aristotle once said, "Give me a fulcrum and I can pry up the earth". Now, with the development of technology, this grand statement can be changed to "Give me an Internet of things and I can sense the earth". The magical Internet of Things brings many surprises and conveniences to people, and the first credit goes to sensors of all kinds, as they detect real information and data in the first place. Here are some applications of IoT sensors:
Wireless temperature and humidity sensors to remind you when it's time to water.
"The greens and lettuce in the field, need to be watered, you see the message I received on my phone prompted me to have to do it immediately. A farm technician calmly told reporters. Since the Internet of Things technology used in planting vegetables above, he can save his mind.
According to him, their farm 40 greenhouses are filled with more than 20 kinds of sensors, wireless temperature and humidity sensors, wireless light sensors and intelligent video systems, wireless sensors placed directly in the field, closely monitor the growth of crops, collect data to the computer monitoring center, and then through the wireless Internet of Things module, the relevant information sent to the farmer's cell phone or tablet computer.
It is reported that this is the farm elaborate intelligent agriculture project. Of particular interest is that a variety of sensors play an extremely important role in perception, for example, while shape sensors, weight sensors, color sensors can monitor the body shape, size, color of the target object to identify the degree of maturity of crops to determine the picking time; for example, carbon dioxide sensors can carry out artificial environmental monitoring of crop growth and promote photosynthesis; the use of flow sensors and computer system to automatically control water irrigation in farmland.
By configuring sensors to monitor crops, we can grasp first-hand field information, realize remote analysis and monitoring, and truly grasp field information in real time to realize smart agriculture.
Multiple sensors to monitor patient characteristics.
IoT sensing and a variety of sensors are also used in the field of medical care, especially for the care of critically ill patients in hospitals, but also show their skills, not bad.
For example, smart humidity sensors and wireless air quality detectors are placed in wards to monitor the temperature and humidity of the air in the ward and the concentration of carbon dioxide in real time, and to accurately measure its dew point and absolute humidity or water content in order to supply the patient with air of the right humidity to help the patient sleep soundly. This is welcomed by many patients.
In the observation ward, doctors use a micro-dust sensor integrated block and a wireless cloud-based fully automated blood pressure monitor to measure the patient's blood pressure, pulse and respiration, sleeping position, and activity status 24 hours a day. Through this remote monitoring, the patient feels no mental pressure from the caregiver while naturally measuring the relevant vital indices, which facilitates the doctor's light grasp and control of the condition.
Accidental gas leak at home, wireless gas leak detector automatically alarm.
Mike, who was at work, suddenly received a message on his cell phone alerting him that there was a gas leak at home, please deal with it. This message scared him, because his 70-year-old mother is sick in bed, if the gas leak, the consequences are unthinkable.
