PH Sensor arduino Analog pH Meter เซ็นเซอร์วัดค่า PH ของน้ำ E-201-C

PH Sensor arduino Analog pH Meter เซ็นเซอร์วัดค่า PH ของน้ำ E-201-C Analog pH Meter (pH Sensor) เป็นเซ็นเซอร์ PH arduino สำหรับวัดความเป็น กรด-เบส ของสารละลายโดยค่าที่วัดได้จะอยู่ในช่วง 0 - 14pH output เป็นแบบ Analog (0-1023) ใช้ไฟเลี้ยง 5V PH SENSOR PRODUCT DESCRIPTION Need to measure water quality and other parameters but haven’t got any low cost pH meter? Find it difficult to use with Arduino? Our analog pH meter, specially designed for Arduino controllers and has convenient and practical connector and a bunch of features. Instant connection to your probe an your Arduino to get pH measurements at ± 0.1pH (25 ℃). For most hobbyist this great accuracy range and it’s low cost makes this a great tool for biorobotics and other projects! It has an LED which works as the Power Indicator, a BNC connector and PH2.0 sensor interface. To use it, just connect the pH sensor with BNC connector, and plug the PH2.0 interface into the analog input port of any Arduino controller. If pre-programmed, you will get the pH value easily. Comes in compact plastic box with foams for better mobile storage. Build your own PH meter gadget, or a water monitoring station for your water tanks. This and our other water sensor devices could make for the ultimate water control device. Use it for your aquaponics or fish tanks or other materials that need measurements.
