Features: Can connect directly to the cloud without an additional gateway, offering high bandwidth and supporting OTA updates as well as rich data interaction. However, they have relatively high power consumption and strong dependence on network stability.
Applicable Scenarios: Suitable for devices powered by mains electricity or continuous power supply, such as smart sockets, cameras, smart light bulbs, and air conditioner companions. These devices have relatively high requirements for network connection stability and need to conduct large-volume data transmission.
Selection Recommendations: If the product is a single-category device with high requirements for network connection and data transmission, WiFi modules should be prioritized. Meanwhile, attention should be paid to parameters of WiFi modules such as frequency band and transmission rate to adapt to different application scenarios and network environments.
Features: Extremely low power consumption, making them suitable for battery-powered devices. They are usually used in short-range direct connection scenarios or as a dual-mode solution combined with WiFi. However, when used independently, their communication range is limited, and a mobile phone or gateway is required as a bridge.
Applicable Scenarios: Commonly used in smart door locks, wearable devices, sensors (such as temperature-humidity sensors and door magnetic sensors), etc. These devices are usually battery-powered, have strict requirements for power consumption, and their communication range is generally within a short distance.
Selection Recommendations: For battery-powered low-power devices that need short-range communication with mobile devices like smartphones, BLE modules are a good choice. If broader network connection capability is required, a dual-mode module combining BLE and WiFi can be considered.
Features: Strong self-networking capability, supporting Mesh networks, with high stability and strong anti-interference ability. However, their cost is higher than that of BLE modules, and they must be connected to the Internet with a matching gateway.
Applicable Scenarios: Suitable for scenarios that require large-scale device networking, such as smart lighting systems, security sensor networks, and environmental monitoring. They can realize stable communication and collaborative work between devices.
Selection Recommendations: If the product is part of a complete ecosystem and needs to support networking and collaborative work of a large number of devices, Zigbee modules are a more appropriate choice. During selection, factors such as the networking capability of Zigbee modules, compatibility of communication protocols, and adaptability to gateways should be considered.
Features: Driven by a motor to rotate the ball screw, converting rotational motion into linear motion. They feature high precision and high rigidity, making them suitable for heavy-load scenarios, but their initial investment cost is relatively high.
Applicable Scenarios: Commonly used in high-precision application scenarios such as precision machining equipment (e.g., tool magazine positioning of CNC machine tools), medical testing instruments (e.g., sample arm driving of biochemical analyzers), and semiconductor packaging (e.g., chip mounting axes).
Selection Recommendations: When the application scenario has extremely high precision requirements (e.g., reaching micron-level precision or higher) and involves large loads, high-precision ground ball screw modules should be selected. Additionally, appropriate screw diameter, guide rail spacing, and base size should be chosen based on the load magnitude and torque requirements.
Features: Driven by a motor to rotate the timing pulley, transmitting power through the engagement between the timing belt and the sliding table. They feature high speed, long stroke, and high cost-effectiveness, but their positioning precision is relatively low.
Applicable Scenarios: Suitable for scenarios that require high speed but not extremely strict precision, such as logistics sorting systems, 3C electronics assembly, and general automated production lines.
Selection Recommendations: If the application scenario requires long-distance high-speed transportation with light loads, timing belt modules should be prioritized. During selection, appropriate timing belt specifications and module models should be chosen based on parameters such as load weight, stroke length, and speed requirements.
Features: Theoretically, they have an infinite stroke, good rigidity, and can be used in working conditions with large loads. However, their cost is not low, they require frequent maintenance, and their installation difficulty is relatively high.
Applicable Scenarios: Suitable for industrial scenarios that require long-stroke and heavy-load transmission, such as automobile manufacturing and heavy machine tools.
Selection Recommendations: When it is necessary to achieve linear motion with ultra-long stroke and large load, gear rack modules are an optional solution. During selection, factors such as the precision and module of the rack, as well as the material and transmission ratio of the gear, should be considered.
