Protecting a PCB from soil and sand is a relatively simple issue, but preventing water ingress is a completely different challenge. By it's nature water can penetrate through the tightest of cracks. In the spirit of ensuring we provide our customers with the best possible products, we challenged our PCB to a 65 hour submergence challenge. This emulates a worst case scenario where the device is unable to float to the surface. A trace of condensation was found in the box after the test was...

At ZP we are proud of the engineering design that has gone into the production of our nitrate rods. The sensors sit in water tight housing preventing the chance of electrical failure and extending the life length of the sensor. The housing is secured to a sleeve adding to robustness and improving the accuracy when aligning. The sensors are stationed 30 cm apart with a depth gauge provided to ensure accurate placement. Wires move up through the rod to the PCB where the signals are processed and...

Using Julia DBA and Djuli, our very own data storage and analysis platforms, we rapidly convert voltage readings obtained from any data logger to concentrations in your desired units. We are aware that data is a powerful tool in precision farming and hence we endeavour to bring usable information at the touch of a button.

Following the release of our new nitrate sensor module, we thought it would be important to mention our recent garden study using commercial Delta-T data loggers. The study successfully identified the optimum method of calibration and accurately identified nitrate values within the expected range. Whilst the sensor modules are compatible with any commercial data logger, it must be recognized that our results were achieved with those manufactured by Delta T. Their data loggers were selected for...

We are excited to announce the release of our new nitrate sensor modules. They are our first independent functional nitrates sensing units which can be used with any commercial data logger for the detection of nitrates in soil. Proven water resistance and robust design they will fare well in the harshest of conditions. Rigorously tested In a vast range of environments and pre-calibrated to achieve reliable results. Stop wasting nitrates and start saving the planet with our budget design

A few weeks ago, we took our nitrate sensor modules to the garden and tested them for nitrates and now we are pleased to report that they respond very well to varying levels of soil nitrate. The sensors take about a day or two to stabilise followed by continuous readings. In order to check if they do respond to an increase in the nitrate content of the soil, we spiked the soil with potassium nitrate (KNO3) solution. All the sensors showed a response to the sudden influx of nitrate, varying in...

The lab is equipped with items like flow hoods, non-ducted fume cupboards; -80, -20 and 4°C storage; incubators (static/shaking); centrifuges (1ml-50ml refrigerated) and bench space. This lab will serve as a hub for several of our projects, most importantly, the Nitrate sensor project. Located close to Central London, the lab is a 15-minute walk from Imperial College and is easily accessible by tube and the overground.

The nitrate sensor module has successfully been through lab testing following which it has now been set in several gardens across UK as a part of our alpha tests. The sensor modules have proven to be robust functional units for estimating nitrate levels in the soil. These units can withstand all weather conditions and provide continuous readings. These tests have shown promising results and we hope to enter the next phase of testing soon. With each level, we move one step forward towards our...
