It is a cost-effective, low-power sensor with an accuracy of ±2°C from 0°C to +70°C (MCP9700A\/9701A) and ±4°C from 0°C to +70°C (MCP9700\/9701) while consuming 6µA (typical) of operating current. Unlike resistive sensors (such as thermistors), the Linear Active Thermistor IC does not require additional signal conditioning circuitry. Therefore, the development overhead of biasing circuits for thermistor solutions can be avoided by implementing this low-cost device. The voltage output pin (VOUT) can be directly connected to the ADC input of a microcontroller. The temperature coefficients of the MCP9700\/9700A and MCP9701\/9701A are scaled to provide 1°C\/bit resolution for an 8-bit ADC with a reference voltage of 2.5V and 5V, respectively. The MCP9700\/9700A and MCP9701\/9701A provide a low-cost solution for applications requiring measurement of relative temperature change. When measuring relative temperature change from +25°C, an accuracy of ±1°C (typical) can be achieved from 0°C to +70°C. This accuracy can also be achieved by applying system calibration to +25°C. In addition, this family is immune to the effects of parasitic capacitance and can drive large capacitive loads. This provides printed circuit board (PCB) layout design flexibility by allowing the device to be located remotely from the microcontroller.

It can be accurately quantified using a sensor that measures the potential difference between two electrodes: a reference electrode (silver\/silver chloride) and a glass electrode that is sensitive to hydrogen ions. This is what forms the probe. In addition, an electronic circuit must be used to properly condition the signal so that we can use this sensor with a microcontroller, such as an Arduino.\u003c\/p\u003e\n\n\u003cp\u003e This analog pH meter is specifically designed to measure the pH of a solution and reflect its acidity or alkalinity.

An internal preheater within the sensor helps achieve ideal sensing conditions, but the datasheet recommends more than 24 hours of warm-up time for optimal accuracy. Due to the internal preheater, this sensor requires more current than most of our I2C Mini Modules. We measured 139 mA for this I2C mini module, so we highly recommend planning a power strategy so your I2C master device delivers no less than 150 mA per sensor. This sensor comes pre-calibrated to the values recommended in the datasheet; however, a final calibration may be required for accurate measurements, as we do not have the equipment for large-scale calibration of these sensors.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n \u003cp\u003e\u003cspan style=\"vertical-align: inherit;\"\u003e\u003cspan style=\"vertical-align: inherit;\"\u003eAll I2C mini modules are designed to operate at 5VDC.

The ideal sensing condition for the MQ9 is 20°C ±2°C with 65% ±5% humidity. An internal preheater within the sensor helps achieve ideal sensing conditions, but the datasheet recommends 48+ hours of warm-up time for optimal accuracy. Because of the internal preheater, this sensor requires more current than most of our I2C Mini Modules. We measured 139mA for this I2C mini module, so we highly recommend planning a power strategy so that your I2C master device delivers no less than 150mA per sensor.

No need to stick your nose in a milk carton anymore, you can build a digital nose with the SGP40 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very slim air quality sensor from the sensor experts at Sensirion, with an I2C interface so you don’t have to manage the heater and analog readout of a MOX sensor. It combines multiple metal oxide sensing and heating elements on one chip to provide more detailed air quality signals.\u003c\/p\u003e\n\n \u003cp\u003eThe SGP40 has a standard hot-plate MOX sensor, as well as a small microcontroller that controls power to the board, reads the analog voltage, and provides an I2C interface for reading. Unlike the CCS811, this sensor does not require extending the I2C clock. We currently have an Arduino library with examples of reading the raw value and also running the Sensirion algorithm for calculating the VOC index, and a Python\/CircuitPython library that can be used with Linux computers like the Raspberry Pi or our CircuitPython boards.\u003c\/p\u003e\n\n\u003cp\u003e This is a gas sensor that can detect a wide range of volatile organic compounds (VOCs) and H2 and is designed to monitor indoor air quality. The SGP40 is the next generation after the SGP30, but it doesn't provide TVOC\/eCO2 values like the SGP30. Instead, the raw signal from the sensor is processed using its software algorithm to give an overall \"air quality\" score from 0 to 500.\u003c\/p\u003e\n\n \u003cp\u003eKeep in mind that this sensor, like all VOC\/gas sensors, has variability, and for accurate measurements, you'll want to calibrate it with known sources. That said, for general environmental sensors, it will give you a good idea of trends and comparability.\u003c\/p\u003e\n\n\u003cp\u003e Another great feature of this sensor is the ability to configure humidity compensation for greater accuracy. An external humidity sensor is required, and the %RH is then written to the sensor via I2C, allowing you to better calibrate the MOX sensor reading and reduce humidity\/temperature-based variations.\u003c\/p\u003e\n\n \u003cp\u003eGood sensor, right? So we've made it easy for you to jump right into your next project. The surface-mount sensor is soldered onto a custom-made PCB in the STEMMA QT form factor, making it easy to interface. The STEMMA QT connectors on both sides are compatible with SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the SGP40 or link it with a wide range of other sensors and accessories using a compatible cable. The QT cable is not included, but we have a variety in the store.\u003c\/p\u003e\n\n\u003cp\u003e Of course, we've broken out all the pins to standard headers and added a 3.3V voltage regulator and level shifting so you can use it with 3.3V or 5V systems, like the Arduino Uno or Feather M4.\u003c\/p\u003e\n\n\u003cp\u003e \u003ca href=\"https:\/\/www.adafruit.com\/product\/3709\" target=\"_blank\" title=\"Reference link\" rel=\"noopener\"\u003e\u003cspan\u003e\u003cstrong\u003eReference link\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":45849359745124,"sku":"AD46492","price":31.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0699\/1344\/4452\/files\/4829-01.jpg?v=1747027834"},{"product_id":"ad49967","title":"CCS811 - SparkFun Air Quality Breakout [SEN-14193] - (AD49967)","description":"\u003cp\u003e\u003cstrong\u003eDescription:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e The CCS811 Air Quality Breakout is a digital gas sensor solution that detects a wide range of Total Volatile Organic Compounds (TVOCs) including carbon dioxide equivalent (eCO2) and metal oxide (MOX) levels.

The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin: it does not require the user to subtract a large constant voltage from the output to obtain its convenient Celsius scale. The LM35 device requires no external calibration or trimming, providing a typical accuracy of ± 1\/4°C at room temperature and ± 3\/4°C over the -55°C to 150°C temperature range. Lower cost is ensured by wafer-level trimming and calibration.
