Octrooi, piagam pendirian Vereenigde OostIndische Compagnie (VOC) yang memuat hakhak istimewa VOC di Nusantara. Pada 1603, VOC memperoleh izin di Banten untuk mendirikan kantor perwakilan dan pada 1610, Pieter Both diangkat menjadi Gubernur Jenderal VOC pertama (16101614), tetapi memilih Jayakarta sebagai pusat administrasi VOC.
Volatile Organic Compounds (VOCs) are sometimes present in applications and can produce crosssensitive readings. The term VOC applies to a wide range of hydrocarbons with different behaviours. At high concentrations of VOC, the sensor background compensation may become overwhelmed and the reading lower than actual.

Sensor API. Tasmota sensor API documentation for sensor driver development. Important things to consider~. There are several I 2 C sensor examples you can take from the development codebase when writing your own and you are encouraged to do this as it is a quick and easy way to see how things fit together.; The Tasmota firmware is essentially intended for ESP8266/ESP8285 WiFi SoC based ...
Wird der VOCSensor direkt an einen USBPort des ioBrokerServers angeschlossen, so müssen dem Benutzer "iobroker" Schreibrechte auf dieses USBGerät erteilt werden. Wie Windows die Rechte der USBGeräte verwaltet ist mir nicht bekannt, daher kann ich keine Aussage über die Möglichkeit der Einbindung des VOCSensors unter Windows machen.

This is a digital VOC (Volatile Organic Compounds) sensor module from Waveshare that incorporates an SGP40 VOC sensor and is designed for air quality monitoring. It can be used to detect and measure airborne particles from wood smoke, natural gas, cigarette/cooking smoke, VOCs from construction activity, paint fumes, etc.
These sensors respond to a broad range of VOCs although they each display a unique sensitivity to certain VOCs or classes of hydrocarbon. The three sensors are all sensitive towards aromatic hydrocarbons. None of the sensors respond to methane. The NMHC sensor and VOC sensor show unique sensitivity towards certain organic compounds.
Can be backordered. Grove Multichannel Gas Sensor V2 provides stable and reliable gases detecting function under the circumstances of any other four sorts of gases. It can detect a variety of gases, besides Carbon monoxide (CO), Nitrogen dioxide (NO2), Ethyl alcohol (C2H5CH), Volatile Organic Compounds (VOC), and etc.
Targeted VOC measurements are useful in controlled environments ( labs, research) where the target compound is used and process control or health and safety risks are required. To measure a targeted VOC, a known correction factor is applied to calculate the relative value from isobutylene that is used for the sensor calibration.
BME680 sensor, an environmental I 2 C sensor with temperature, humidity, barometric pressure and gas.. The BME680 takes those sensors to the next step in that it contains a small MOX sensor. The heated metal oxide changes resistance based on the volatile organic compounds (VOC) in the air, so it can be used to detect gasses alcohols such as Ethanol, Alcohol and Carbon Monoxide, and perform ...
A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
The Environment Sensor HAT is designed for the Raspberry Pi series of boards, with rich onboard resources including an ambient light sensor, VOC sensor, IR / UV sensor, gyroscope, accelerometer, magnetometer, barometer, temperature humidity sensor, etc. This hat utilizes the I2C bus for communicating with Raspberry Pi, freeing up valuable GPIO pins for use with other things.
3. Can MOS VOC sensors be used for ventilation control?
