HereLab Agriculture Hub

Want realtime soil moisture, drip line psi and rain info? You can plug in Watermarks, tie in a transducer and hook up temp and a rain gauge. Oh, and one season on one C-cell battery.

Our Ag Hub is an AgTech Design Template 

We work with farmers, sensor manufacturers and data people to design the best field, barn and greenhouse sensing tools.

Onboard sensor interfaces for soil, water, irrigation and weather enable rapid development and POC deployments.

And, our code libraries, for an expanding number of sensors, enable you to use familiar sensors and send realtime data — fast.

Design to Purpose

We design to solve real world problems. Modularity and reference designs allow us to quickly design to fit the purpose. With our use-driven boards and code libraries we can rapidly retool to design single purpose hardware in our rapid prototype lab. Contact us for a quick consultation.

Data Agnostic

We can point all data to your preferred provider. Or we can recommend data services to meet your need. We don’t have one solution for your connectivity. You decide the best data and business model to suit your information and business needs.

HereLab Urban Hub 

Want motion, light and sound detection? Need to monitor water flow, humidity or CO2? With our reference designs your POC won’t cost you years.

Our Urban Hub is a “Smart City” Design Template

Our Urban Hub is an IoT testbed. Managed service providers and product developers can quickly deploy “smart city” POCs and test business models.

Our Urban Hub engineering and code reference design can onboard most any sensor quickly and our telemetry libraries can test data send assumptions in a snap.

Whether you’re outfitting a campus or developing a single-purpose product our reference designs will accelerate your IoT initiative.

Efficiently Lowering Cost

We work with managed service providers, architects and designers to help you design, develop and deploy suitable, low cost solutions.

Some “smart city” solutions lock you in to platforms. The engineering costs required for those expensive devices gets passed along to the end customer. We don’t work that way.

HereLab is a product and building manager partner. We don’t pass along cost — we pass along knowhow. That matters when getting tested building solutions to scale.

Sensor Integrations

For all engineering integrations we also develop firmware and software for data and connectivity.
