 Sensor Output Forms

For the ambient temperature and humidity and barometric pressure sensors, their output forms usually include the following:

1. analog signal output

   - Voltage output: The sensor converts the measured physical quantity into a voltage value for output through internal circuitry. For example, a temperature measurement may correspond to a voltage output proportional to the temperature, and similar voltage outputs may be used for humidity and barometric pressure measurements.

   - Current Output: Similar to a voltage output, a sensor may convert a measurement into a current for output. This type of output may be more stable in some applications because the current signal is less susceptible to line resistance.

2. Digital Signal Output

   - Serial communication interfaces: e.g. RS485 These interfaces allow the sensor to communicate with a computer, microcontroller, or other digital device to transfer measured data. Among them, RS485 interface is especially common in industrial applications because of its strong anti-interference ability and long transmission distance.

3. Other special output forms

   - Switching output: In some cases, the sensor may only need to output a simple switching signal to indicate whether the measured value exceeds a certain threshold. For example, when the temperature exceeds a set point, the sensor may output a high level signal to trigger an alarm or control device.

   - Mixed analog/digital output: Some sensors may provide both analog and digital output forms to meet the needs of different application scenarios.

 Temperature and humidity sensor power supply

Temperature and humidity sensors have a variety of power supply methods to meet the needs of different applications:

1. DC power supply

   - Common way: DC 12V or 24V, suitable for fixed installation and stable power supply occasions.

2. Battery powered

   - Portable or remote area use: for sensors that need to be moved or are not easily connected to an external power source.

3. Solar powered

   - Outdoor agricultural applications: especially suitable for outdoor agricultural applications, to achieve long-term maintenance-free operation, especially for remote or well-lit areas.

Selection of the appropriate power supply needs to be based on the use of the sensor environment, continuous operation requirements and maintenance convenience to decide. In the agricultural field, taking into account the long-term stability of the equipment and maintenance costs, low power consumption and renewable energy power supply scheme is often preferred.

 Application Scenarios for Ambient Temperature and Humidity Sensors

- Weather monitoring: Used in weather stations to provide accurate weather data.

- Environmental monitoring: used for monitoring environmental temperature, humidity and air pressure, assessing environmental quality and warning of natural disasters.

- Industrial Control: Used for temperature, humidity and air pressure monitoring of industrial equipment to ensure the normal operation of the equipment.

How to choose temperature and humidity sensors for agriculture?

When choosing a temperature and humidity sensor for agriculture, you need to consider the following key factors:

1. Measurement accuracy and stability

   - Accuracy: Choose a sensor with an accuracy between ±2%RH and ±5%RH to ensure data reliability.

   - Stability: A stable sensor reduces the accumulation of errors in long-term use.

2. Environmental adaptability

   - Protection class: at least IP65 to resist dust and rain from farmland.

   - Corrosion resistance: Choose sensors made of stainless steel or corrosion-resistant materials for different soil and climate conditions.

   - Temperature range: Covering -30℃ to 70℃ to adapt to extreme weather.

3. Low power consumption

   - Power consumption: Agricultural sensors are often deployed in remote areas, and low-power or solar-powered sensors are more convenient for long-term use.

4. Installation and Maintenance

   - Installation: Simple and easy to install, easy for farmers to operate.

   - Maintenance: low maintenance cost, preferably supporting simple calibration on site.

5. Signal output

   - Output form: choose the output method suitable for agricultural automation system, such as 4-20mA or RS485, for remote monitoring and control.

6. Calibration Period

   - Calibration period: Choose sensors with short calibration period or free of calibration to reduce maintenance frequency.

7. Response time

   - Response time: A fast response sensor can reflect environmental changes in time, which is especially important for crop growth.
