What others say about us

“Data in combination with plant parameters are a crucial recipe for giving proper advice. The sensors of Sendot enable us to develop insights we did not have before. This empowers us to give our customers additional feedback to achieve best possible results”

Bonte de JongAdvisor - Fytoconsult

“Monitoring with sensors has become essential in research projects. The SenBox has enabled us to monitor real-time plant performance and log data related to the rootzone such as Oxygen and pH. In addition, the Photosynthesis-efficiency sensors reveals plant stress which enables me to react quickly if trends are deviating.”
