With high anti-interference ability, high stability, and high sensitivity, this Arduino-compatible oxygen sensor can be widely applied to fields like portable devices, air quality monitoring devices, and industries, mines, warehouses, and other spaces where the air is not easy to circulate. I will create a Frizzing plan : where i take care for the peripheryīTW see more infos : in-shop.The Gravity: I2C Oxygen Sensor is based on electrochemical principles and it can measure the ambient O2 concentration accurately and conveniently. A digital precision current sensor module that measures voltage, current and power of electronic modules and devices up to 26V and 8A with a relative error. +-+ +-+įurther steps: i think about the interface: DS18B20 circuit, DS18B20 data sheet : DALLAS, alldatasheet, datasheet. So here's a schematic drawing in advance - how I imagine it KIT0017 STARTER KIT ARDUBLOCK GRAVITY DFRobot 2578 pcs Stock RFQ 2151B VIBROBUG. Thisĭevice does not include a pH probe/sensor/electrode.ītw: i think i will stick to the b.- the Atlas Scientific™ EZO™ class embedded pH circuit This device reads pH from a pH probe/sensor/electrode.
The pH-EZO™ pH circuit, can work with any off-the-shelf pH probe/ sensor/electrode. With proper configuration the EZO class pH circuit, can meet, orĮxceed the accuracy and precision found in most bench top laboratory grade pH meters. This EZO class pH circuit, offers the highest level of stability and accuracy.
The Atlas Scientific EZO™ class pH circuit, has a flexible calibration protocol, allowing for single point, two point, or three point calibration. TI E2 by : The Atlas Scientific EZO™ītw: I note that the Atlas Scientific EZO has a pH resolution of +/-0.002 - well i do not really need that high resolution!!! So i guess that i have to choose the DFRoboat Gravityīut here the comparison: which one is the best one!? to test water, Coffee, Tea, and so on (beverages)ĭFRobot Gravity Analog pH Sensor / Meter Kit For ArduinoĪquakultur: ANALOG PH-SENSOR / METERSPEZIFIKATIONĮZO TM class embedded pH circuit This is an. EZO TM class embedded pH circuit: This is an. Then I learn the calibration method that determines the accuracy and accuracy of the sensor.īut - as I said: actually I would like to get around the calibration.ī. Last but not least - if the system has to be calibrated (which I don't necessarily "have to" have - then I would just "take it with me". I think I can learn a lot from this project Something about the construction and functioning of the pH sensor. I want to make a simple ph meter and display the ph value on an OLED/LCD display.
