{"product_id":"onion-adc-expansion-discontinued","title":"Onion ADC Expansion [Discontinued]","description":"\u003cp\u003eThe Omega ADC Expansion will bring a new world – the analog world – directly to your Omega2 projects. Based on the ADS1115 analog-to-digital converter chip, this Expansion provides 4 analog input channels, each with 16 bits of precision at a maximum of 860 samples per second, and communicates with your Omega using I2C.\u003c\/p\u003e\n\n\u003cp\u003eWith this Expansion, your Omega will be able to read and interpret analog signals! This opens the door to a whole bunch of sensors. Directly connect up to 4 analog signals to the female header on the board and safely sample analog voltages from -6V to +6V. There’s also power and ground headers for each analog input, providing an easy way to power your sensors.\u003c\/p\u003e\n\n\u003cp\u003eWe’re huge fans of the Grove family of sensors, actuators and controllers, so we’ve included 3 Grove connectors right on the ADC Expansion. Two connectors are analog, and the third is digital I2C.\u003c\/p\u003e\n\n\u003cp\u003eA nice bonus about the ADC Expansion is that it’s stackable, each Omega2 can support up to 2 stacked ADC Expansions, giving you 8 analog input channels in total. The switch on the side of lets you change the I2C address (between 0x48 and 0x49).\u003c\/p\u003e\n\n\u003cp\u003eSetup is a breeze, just plug it into the Expansion Header on a Dock and you’re all set. Take a look at our guides to get started connecting sensors and Grove devices, and reading analog signals from the Omega’s Linux command line.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical Details\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eAnalog input channels: 4\u003c\/li\u003e\n\t\u003cli\u003eSignal resolution: 16 bits\u003c\/li\u003e\n\t\u003cli\u003eSamples per Second: programmable from 8 to 860\u003c\/li\u003e\n\t\u003cli\u003eInput analog voltage range: -6V to +6V\u003c\/li\u003e\n\t\u003cli\u003eStackable: Yes, up to 2 ADC Expansions, providing 8 analog input channels\u003c\/li\u003e\n\t\u003cli\u003eChipset: TI ADS1115\u003c\/li\u003e\n\t\u003cli\u003eCommunication Protocol to Omega: I2C\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCompatible analog sensors\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eTemperature: TMP36 \/ LM335\u003c\/li\u003e\n\t\u003cli\u003eHumidity: IH-4030\u003c\/li\u003e\n\t\u003cli\u003eLight: Photodetector \/ ALS-PT19 \/ BPW34\u003c\/li\u003e\n\t\u003cli\u003eWater Level \/ PN-12110215TC-8\u003c\/li\u003e\n\t\u003cli\u003eCurrent: ACS723\u003c\/li\u003e\n\t\u003cli\u003e Hall-Effect: AH1815\u003c\/li\u003e\n\t\u003cli\u003eAny voltage output sensor from -6V to +6V\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Onion","offers":[{"title":"Default Title","offer_id":48623991849178,"sku":"lzq1789680592758","price":13.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/onion-adc-expansion-discontinued_1.png?v=1789680597","url":"https:\/\/memoryfoamwear.shop\/products\/onion-adc-expansion-discontinued","provider":"My Store","version":"1.0","type":"link"}
