The first one (PCB technology) provides robust sensors with PET film which can be exposed to harsh environment. The second (ink-jet technology) can manufacture sensors on flexible substrates (foils and papers). The third (screen printing technology) has been used to implement a thick-film sensor. In addition to this, a multi-sensor cloudbased electronic system with autonomous power supply (solar panels) for air and water quality monitoring has been described. Finally, a flexible and modular hardware platform for remote and reliable sensing of environmental parameters has been presented %K humidity sensor %K pH sensor %K sensitivity %K stability %K sensor node %U http://casopisi.junis.ni.ac.rs/index.php/FUElectEnerg/article/view/3068
