Hello friends,
I am working on WSN based project for this i want to measure parameters like soil moisture,soil temperature,soil pH. The sensors which i saw are very expensive so can anyone please suggest me any sensor which is around 24$ to 30$(for each parameter). Please suggest me soon, because i have to start with there signal conditioning as soon as possible.And it takes around two months for shiping and all these stuff.
Thank you.

    Hi

    I have faced the same problem while I was trying to find a low cost pH measurement device to measure the change in pH of Human sweat during cardio vascular exercise. But most sensors are extremely costly.

    The best solution I feel is to go for titration, and measure the volume of the titrant using a sensor. To detect the end point, a colur sensor can be integrated without adding much to the cost.
