i need to u, i am confuse or no idea of how to interface of soil moisture sensor in to lpc 2148 so help me or give me information of how to solve this problem..i will wait your reply...

soil moisture sensors interfacing with arm7 lpc2148

Soil moisture sensor

Soil moisture sensors measure the water content in soil. A soil moisture probe is made up of multiple soil moisture sensors.

This Soil Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help.Insert this module into the soil and then adjust the on-board potentiometer to adjust the sensitivity. The sensor would outputs logic HIGH/LOW when the moisture is higher/lower than the threshold set by the potentiometer.With help of this sensor, it will be realizable to make the plant remind you : Hey, I am thirsty now, please give me some water.

ARM7 LPC2148 Slicker Board The ARM7 LPC2148 Slicker board is specifically designed to help students to master the required skills in the area of embedded systems. The kit is designed in such way that all the possible features of the microcontroller will be easily used by the students. The kit supports in system programming (ISP) which is done through serial port. NXP’s ARM7 (LPC2148), ARM Slicker Kit is proposed to smooth the progress of developing and debugging of various designs encompassing of High speed 32-bit Microcontrollers. Temperature Sensor DS1820 is a temperature sensor which is small sensor. The output of sensor converted to digital that easy connecting with microcontroller. Interfacing ds1820 Fig. 1 shows how to interface the ds1820 to microcontroller. As you can see the first pin is connected to GND, the third pin is connected to VCC & the second pin is connected to the Microcontroller. So when the temperature is sensing, it give the sensor reading to controller.
