Which sensors can you use to collect data in horticulture?Sensors are increasingly used in the horticultural sector. Sensors provide valuable data that you, as a grower, can use to optimise your cultivation and thus achieve higher yields. Different sensors are available. Each one can be used to measure a different factor. In this article our specialist shows you the different types of sensors and how to use them to collect data. 

Soil moisture sensor for potting soil

A soil moisture sensor for potting soil is intended to monitor the volumetric water content (VWC) and can be used for all soil types. With the help of real-time data from soil sensors, you can adjust the irrigation and feeding schedule. Notifications indicate when a crop requires irrigation or drainage. This easily prevents the harmful effects of overwatering such as standing water, overheating of salts, root rot, mould and mildew.

Soil moisture sensor for substrate

A substrate soil moisture sensor is designed to measure water flow, electrical conductivity and temperature in the substrate. This sensor also offers data that you can use to adjust the irrigation and feeding schedule.

Temperature sensor

With a temperature sensor you measure the surface temperature of the crop. This temperature can deviate from the air temperature due to factors such as high light irradiation, cold outside air and the heat radiation of tubes in the greenhouse, but can also occur in cases of low humidity or a lot of radiation.

The plant temperature sensor provides real-time data from any plant, fruit or leaf. This way you can compare temperatures between different greenhouses. You will also receive alerts as soon as the temperature rises or falls further than the predetermined limits. Use this sensor in combination with a temperature and humidity sensor to determine the dew point of individual plants.

Temperature and humidity sensor

A temperature and humidity sensor records real-time granular data on environmental conditions at various locations, from greenhouses to sealed cold storage containers. Set your parameters via the ZENSION dashboard and get notifications when the temperature or humidity rises or falls outside your specified limits.

PAR sensor

A PAR sensor measures the light intensity in the greenhouse, i.e. the force of natural sunlight. PAR light is the main component for photosynthesis. A PAR measurement measures the light spectrum between 400 nanometers and 700 nanometers. In case of incident sunlight, a PAR measurement can be used, for example, to provide insight into the effectiveness of a chalk or shielding agent on the greenhouse deck. 

Oxygen sensor

A good oxygen level in the substrate is important for the overall root quality and water and nutrient absorption of the roots. In addition, a good oxygen level contributes to healthier roots so that the plant can better defend itself against pathogenic fungi. The irrigation strategy influences these factors. With an oxygen sensor you can measure the amount of oxygen in the substrate and thus optimize the irrigation strategy.

Pointed microclimate sensor (dew point)

A pointed microclimate sensor uses a wax temperature in combination with temperature and humidity measurements to determine the VPD, dew point, humidity and temperature at crop level. With this sensor you are able to better determine the heating needs, save unnecessary energy expenditure and reduce the risk of fungi and diseases.

Chlorophyll fluorescence sensor

A chlorophyll fluorescence sensor provides insight into the maturity stage of fruits such as tomatoes, cucumbers, peppers or zucchini or into the growth force of a crop. The sensor gives an indication of the photosynthesis activity in the fruit or leaf. In combination with other parameters such as irradiation and temperature, this gives direction to guaranteeing the quality of fruit in the chain or identifying growth limiting factors in the cultivation. This value may determine the time of harvesting, packaging, duration of storage and transport and the sell-by date in supermarkets, for example.
