I had never listen about such a device. NPK and fertilizers are very useful plant food for all plant. They increase the productivity of plant and soil. But some act as toxic for plant. In such case knoe details the composition of fertilizer is very important. It is quite difficult to know the composition. After reading this blog I think it is now becone easy by using the above instrument. It is good news for our farming sector as well as fertilizer production industries.organic plant fertilizer
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
