Sensors

This chapter describes the standard instruction sets of sensors. These standard instruction sets are classified into the instruction sets and status sets used to control devices. Tuya provides a powerful cloud control model for sensors. You can implement device control and status interactions in JSON data format.

Application scenarios

Through cloud control, sensors help you implement remote monitoring and smart security features. Sensors are convenient, real-time, smart, and collaborative, thereby improving security and management efficiency. By calling cloud development OpenAPI, you can send standard instructions to a device, and thus control various functions. For example, trigger alarms and implement monitoring and environmental detection. Meanwhile, the device reports its standard status to return the current status and data of the device. This way, the following targets can be achieved at ease:

• Remote management and control: Based on cloud control, users can remotely manage and monitor sensors anytime and anywhere without being physically present, in a more convenient and flexible way.
• Real-time data and alerts: Receive sensor data in real time and send alerts and notifications to users, helping to promptly detect and respond to potential threats or emergencies.
• Big data analytics and smart decision-making: Perform data analytics and mining on sensor data collected in the cloud. Provide more accurate support to make informed decisions, helping optimize strategies and resource allocation.
• Application integration and scalability: Integrate with other smart systems, applications, and platforms to achieve functional extensions and collaborative operations. This way, improve overall performance and user experience.

Features

Smart sensors have a myriad of functionalities:

• Alarm: Trigger alarms, send notifications, and more.
• Monitoring: View live video, take snapshots, and more.
• Environmental detection: Detect temperature and humidity, gas, smoke, and PM2.5.
• Sensor: Monitor door and window status, vibration, water immersion, and human movement.
• Smart lock: Unlock the door, query status, and more.

You can use specific instructions to control and interact with sensors depending on varied functional requirements. For more information about functional descriptions and implementations, see the following topics.
