We present the work on the development of wireless pH measuring device. The system consists of measuring electrode, embedded hardware and two way wireless transceiver. Thus this device can be implemented to monitor the pH level of a river, pond or lake or any water bodies remotely. This is a low cost and versatile system which is easy to install and has a very few steps for its operation. The system is very reliable and suitable for real time application. This system is incorporated with various intelligent error detection protocols which makes the system efficient. The system is designed using ATmega 328, 8 bit microcontroller based embedded system platform, glass electrode has been used as a pH sensor and wireless communication is achieved by using IEEE 802.15.4 compatible wireless transceiver. There is also a control algorithm for generation of the alarm signal if the pH value measured does not come in the range of the preset value.
