New Sensor Technologies in Agriculture

Technology has begun to play an essential part in the agricultural system's sustainable intensification, as it decreases labor time and costs while also improving agricultural practices

Fremont, CA: Technology plays a critical part in the agricultural system's long-term sustainability. Scientists have discovered that using sensors in agricultural farming has considerably enhanced growth and yield while also lowering production expenses. Application of sensors in agriculture and other industries have grown fast as the Internet of Things (IoT) technology has advanced. Temperature, humidity, soil content, soil moisture, soil pH, light intensity, and pathogenic infestation are all examples of sensors employed in the agricultural system. These sensors can track various stages of plant development and the settings in which they are cultivated.

Some of the new innovations in agriculture sensors

Location sensors

Longitude, latitude, and altitude, or topographic qualities, are used by location sensors to determine longitude, latitude, and altitude, which are useful in precision agriculture positioning. To triangulate a position, at least three satellites are usually necessary. This sensor is used in vineyards to enhance crop development and yield patterns. They're also helpful for deciphering yield and weed maps.

Electrochemical sensors

This sensor is used to keep track of the soil's pH and nutrient concentration. The sensor electrodes aid in detecting certain ions in the soil, which is used to determine the soil's ionic profile.

Optical sensors

This sensor uses light to determine various soil qualities. Optical sensors work based on measuring distinct frequencies of light reflectance in the mid-infrared, polarised, and near-infrared light spectrums. Vehicles, drones, and satellites can all be equipped with optical sensors. Plant color and soil reflectance are recorded, which can be processed and evaluated for scientific purposes. Optical sensors can also be used to determine the amount of organic matter and moisture in the soil.

Mechanical sensors

This sensor is used to determine how compact the soil is. The probe is placed into the soil, and load cells and strain gauges are used to measure the forces acting.
