Temperature and humidity sensorIt has a high temperature coefficient of resistance, sensitive induction, high resistivity, small component size, and a linear relationship between resistance value and temperature change. Within the temperature measurement range, its physical and chemical properties are stable, with good long-term reproducibility and high measurement accuracy. (If users have special needs, they can use their own sensors)
System functions and advantages:
The system has a clear and highly integrated structure, easy installation and operation, and is suitable for various usage environments. The user interface fully considers the personalized needs of customers, and the system runs stably.
◆ Automatically record real-time updates and automatically record temperature and humidity values. All historical records and related data of temperature and humidity are true and reliable, and stored in a reliable manner
◆ Easy to query and retrieve historical temperature and humidity data records, temperature and humidity curves, temperature and humidity warning information, temperature and humidity limit information, limit handling measures and rectification prompts, environmental assessment of monitoring points, monitoring point faults, geographical location of monitoring points, and other information for any fixed and mobile monitoring points within the vegetable greenhouse.
◆ Complete, accurate, and flexible recording and printing will automatically record the temperature and humidity values and alarm information of all measurement points at the scheduled time, forming searchable and printable historical records, historical curves, and reports.
The flexible alarm function includes computer sound and light alarm, on-site measurement point sound and light alarm, preset location (duty room) sound and light alarm, mobile phone alarm, email alarm, etc.
When calibrating the accuracy of the system for online calibration of sensors, there is no need to disassemble the sensor, only software settings are needed.
The system has strong scalability, and the measurement points can be added arbitrarily within a certain range.
◆ Easy installation, convenient and reliable wiring.
Low power and low-power design: * comes with a self-contained power management solution, equipped with a small capacity UPS power supply.
System features:
◆ Long distance: The recognized distance is 80m (normal distance is 0-50 meters, and an additional antenna needs to be configured for 50-80 meters), and the recognition distance is adjustable.
◆ Conflict prevention: Advanced collision prevention technology can simultaneously recognize more than 200 markings per second.
High speed: The recognition speed can reach 200 kilometers per hour.
◆ Security: Encryption algorithms and authentication ensure data security and prevent link eavesdropping and data cracking.
◆ Directionality: It can achieve directional and non directional recognition.
High reliability: -40 ℃ -85 ℃, shock resistant.
Cost effectiveness: All use 0.18uM chips, resulting in lower costs.
Power consumption: ultra-low power consumption, healthier and safer.
◆ Transmission: Open ISM microwave frequency band, no application or payment required.
◆ High anti-interference ability: No special requirements for various interference sources on site. High anti-interference ability:
◆ Temperature characteristics: ± 0.1 ℃ (if a wider temperature range is required, it needs to be specially determined)
◆ Humidity characteristics: ± 2% H (if a wider humidity range is required, special customization is required)
Measurement time interval: At least 1.5S is required (if faster is needed, special customized development is required)
