It features a wide operating voltage range and allows for relatively high data rates; this particular unit is tuned for a 56 kHz carrier frequency. This is the IR receiver used in the Pololu IR Beacon. ## Pricing - **Price:** $6.10 (inc GST) — $5.55 AUD, exc GST - **Quantity discounts:** 10+ $5.33 (exc GST) · 25+ $5.15 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 21 and Aug 24. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-837:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/POLOLU-837:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description This IR demodulator from Vishay is a general-purpose receiver for IR-based remote-control projects. It is optimized for data rates up to 4000 bits/s and bursts as short as six cycles, and the detector’s epoxy package serves as an infrared filter that helps eliminate noise from visible light sources. The operating voltage range is broad enough for 5 V and 3.3 V logic, and unlike some receiver modules, the TSOP34156 allows for continuous reception. The module’s output signal can be directly connected to a microcontroller; no additional external components are required. For a similar IR detector that is tuned for a 38 kHz carrier frequency, see the [Vishay TSOP38438](https://core-electronics.com.au/vishay-tsop38438-ir-receiver-module-38khz.html). **Modulated IR detector comparison** | Part | TSOP34156 | [TSOP38438](https://core-electronics.com.au/vishay-tsop38438-ir-receiver-module-38khz.html) | [TSSP58P38](https://core-electronics.com.au/vishay-tssp58p38-ir-detector-module-38khz-automatic-gain-3-pack.html) | [TSSP58038](https://core-electronics.com.au/vishay-tssp58038-ir-detector-module-38khz-fixed-gain-3-pack.html) | |---|---|---|---|---| | Intended function | IR remote control | brightness/proximity sensing | predictable modulated IR presence sensing | | Modulation frequency | 56 kHz | 38 kHz | 38 kHz | 38 kHz | | Gain (sensitivity) | automatic but inaccessible | automatic, predictable | fixed high gain | | Output | binary (data) | analog (pulse width) | binary (on/off) | | Update rate | a few **kHz** | a few **Hz** | a few **kHz** | **Specifications** - **Operating Voltage:** 2.7 V to 5.5 V - **Carrier Frequency:** 56 kHz - **Max data rate:** 4000 bps - **Package:** Through-hole with 0.1" lead spacing See the resources tab for the TSOP341 datasheet. **People often buy this product together with:** | [![Sharp GP2Y0A21YK0F Analog Distance Sensor 10-80cm](https://core-electronics.com.au/attachments/localcontent/0J149_3773df07dd.jpg)](https://core-electronics.com.au/sharp-gp2y0a21yk0f-analog-distance-sensor-10-80cm.html) | [Sharp GP2Y0A21YK0F Analog Distance Sensor 10-80cm](https://core-electronics.com.au/sharp-gp2y0a21yk0f-analog-distance-sensor-10-80cm.html) | |---|---| | [![Pololu IR Beacon Transceiver Pair](https://core-electronics.com.au/attachments/localcontent/0J9830_58158b8bef.jpg)](https://core-electronics.com.au/pololu-ir-beacon-transceiver-pair.html) | [Pololu IR Beacon Transceiver Pair](https://core-electronics.com.au/pololu-ir-beacon-transceiver-pair.html) | |---|---| | [![Pololu Carrier with Sharp GP2Y0D810Z0F Digital Distance Sensor 10cm](https://core-electronics.com.au/attachments/localcontent/0J1178_43271fb4d7.jpg)](https://core-electronics.com.au/pololu-carrier-with-sharp-gp2y0d810z0f-digital-distance-sensor-10cm.html) | [Pololu Carrier with Sharp GP2Y0D810Z0F Digital Distance Sensor 10cm](https://core-electronics.com.au/pololu-carrier-with-sharp-gp2y0d810z0f-digital-distance-sensor-10cm.html) | |---|---| **File downloads** - **TSOP34156 datasheet (470k pdf)** ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/v/i/vishay_tsop34156_ir_detector_module_56khz__pololu_837__00.jpg)
