A distributed sensor grid may be used to monitor the growth conditions of plants in an agricultural environment. In one example, a distributed sensor grid may include sensors that are arranged as a grid defined by a vertical axis and a first horizontal axis. The sensors may each be coupled to a cable and/or a port that provides operating power and/or network communications access. In some implementations, a plurality of lighting fixtures disposed in the agricultural environment may be configured to provide the power and network communications access to one or more sensors, thus alleviating use of excess cabling for connectivity and simplifying installation. The sensors may be correspondingly disposed within the vicinity of respective lighting fixtures to monitor growth conditions for a portion of the agricultural environment. The sensors used may also be packaged as an integrated sensor assembly, further simplifying installation and deployment.
