The TSL2561 lumi­nos­i­ty sen­sor is an advanced dig­i­tal light sen­sor, ide­al for use in a wide range of light sit­u­a­tions. Com­pared to low cost CdS cells, this sen­sor is more pre­cise, allow­ing for exact lux cal­cu­la­tions and can be con­fig­ured for dif­fer­ent gain/timing ranges to detect light ranges from up to 0.1 — 40,000 Lux on the fly. The best part of this sen­sor is that it con­tains both infrared and full spec­trum diodes! That means you can sep­a­rate­ly mea­sure infrared, full-spec­trum or human-vis­i­ble light. Most sen­sors can only detect one or the oth­er, which does not accu­rate­ly rep­re­sent what human eyes see (since we can­not per­ceive the IR light that is detect­ed by most pho­to diodes)New! As of June 3, 2014 we are ship­ping a ver­sion with a 3.3V reg­u­la­tor and lev­el shift­ing cir­cuit­ry so it can be used with any 3–5V power/logic micro­con­troller.The sen­sor has a dig­i­tal (i2c) inter­face. You can select one of three address­es so you can have up to three sen­sors on one board — each with a dif­fer­ent i2c address. The built in ADC means you can use this with any micro­con­troller, even if it does­n’t have ana­log inputs. The cur­rent draw is extreme­ly low, so its great for low pow­er data-log­ging sys­tems. about 0.5mA when active­ly sens­ing, and less than 15 uA when in pow­er­down mode.Of course, we would­n’t leave you with a datasheet and a “good luck!” — we wrote a detailed tuto­r­i­al show­ing how to wire up the sen­sor, use it with an Arduino and exam­ple code that gets read­ings and cal­cu­lates lux TECHNICAL DETAILSApprox­i­mates Human eye ResponsePre­cise­ly Mea­sures Illu­mi­nance in Diverse Light­ing Con­di­tionsTem­per­a­ture range: ‑30 to 80 *CDynam­ic range (Lux): 0.1 to 40,000 LuxVolt­age range: 2.7–3.6VInter­face: I2CThis board/chip uses I2C 7‑bit address­es 0x39, 0x29, 0x49, selec­table with jumpersDown­loads:DatasheetPCB lay­out files — pub­lic domain
