Product details
Overview
FS1023-1001-DG from Renesas Electronics is a calibrated gas flow sensor module using thermopile-based calorimetric sensing for 0–35 L/min air/nitrogen flow measurement. It delivers linear analog voltage (0.5–4.5 V) and 12-bit digital I²C output (409–3686 counts), operates at 5 V, and achieves <5 ms response time in ventilator and process control systems.
For engineers reviewing the FS1023-1001-DG datasheet, FS1023-1001-DG pinout, FS1023-1001-DG application, or FS1023-1001-DG equivalent, key selection criteria include its dual-output interface, ±1.5% typical flow accuracy at 25°C, solid thermal isolation architecture, resistance to vibration/pressure shock, and compatibility with standard 3/8″ ID tubing interfaces.
Technical Context
The FS1023-1001-DG implements a calorimetric flow measurement principle using a thermopile sensor element with solid-state thermal isolation and protective Parylene coating. Its signal chain includes on-module analog conditioning and a 12-bit digital output path via I²C (default address 0x50, 100/400 kHz).
Electrical operation is specified across 0–85°C ambient temperature and up to 30 PSI common-mode pressure. The module outputs two synchronized flow representations: analog voltage referenced to VDD and digital counts with checksum-verified integrity, both traceable to nitrogen calibration at 1 bar and 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Flow Range | 0–35 L/min for air or nitrogen - defines full-scale measurable volumetric flow under calibrated conditions. |
| Analog Output | 0.5 V at 0 L/min, 4.5 V at 35 L/min - provides ratiometric, linear voltage output directly usable by ADCs without external scaling. |
| Digital Output | 409–3686 counts over range - 12-bit resolution (LSBs valid in high byte) with checksum-protected I²C read sequence. |
| Response Time | <5 ms (10–90% rise) - enables real-time closed-loop control in fast-dynamic gas delivery systems like ventilators. |
| Supply Voltage | 5 V nominal (2.7–5.5 V absolute max) - compatible with standard industrial logic rails and simplifies power design. |
| Flow Accuracy | ±1.5% typical reading error at 25°C - calibrated against nitrogen at 1 bar, enabling predictable system-level error budgeting. |
Pinout & Package
The FS1023-1001-DG is housed in a 58.0 × 31.5 mm MOD0D1 surface-mount module with a 6-pin crimp-style board connector (e.g., JST PHR-6 receptacle). Pin 6 is NC (not connected); all other pins are electrically bonded and functionally defined.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | Accepts 5 V nominal supply; supports 2.7–5.5 V operating range with 21 mA typical current draw. |
| 2 - GND | Reference ground | Common return for analog output, digital interface, and internal sensor biasing. |
| 3 - Output | Analog flow signal | Linear 0.5–4.5 V output proportional to flow rate; ratiometric to VDD. |
| 4 - SDA | I²C data line | Open-drain bidirectional serial data line; requires external pull-up to VDD. |
| 5 - SCL | I²C clock line | Open-drain clock input; synchronizes 100/400 kHz I²C reads of 12-bit flow data + checksum. |
| 6 - NC | No connection | Not internally bonded; must remain unconnected per design specification. |
Key Features
| Feature | Design Value |
|---|---|
| Thermopile sensing element | Delivers superior signal-to-noise ratio vs. resistor-based flow sensors, improving low-flow detection sensitivity. |
| Solid thermal isolation | Eliminates fragile membranes or cavities, enhancing mechanical robustness against vibration and pressure shock. |
| Dual-output interface | Simultaneous analog voltage and I²C digital output enable flexible integration-no external ADC or protocol translation required. |
| Calibrated linear output | Factory-trimmed transfer function eliminates need for system-level calibration; equations provided for direct flow calculation. |
| Low flow resistance | Minimizes pressure drop across sensor body, reducing impact on upstream/downstream pneumatic system dynamics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gas flow sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Sensirion SFM3300-D | Measures 0–250 sccm (0.00025 L/min) full scale; uses thermal mass flow principle with digital-only I²C output; no analog output. | Targeted at microflow applications (e.g., leak testing), not volumetric flow in ventilators or gas meters. | Select SFM3300-D only when sub-L/min resolution is required and analog interface is unnecessary. |
| Honeywell AWM720P1 | Analog-only output (0–5 V), 0–10 L/min range, no I²C interface; based on piezoresistive bridge; higher power consumption (~30 mA). | Suitable for cost-sensitive, low-range analog-only systems where digital diagnostics or redundancy are not needed. | Choose AWM720P1 if system lacks I²C capability and flow range ≤10 L/min suffices. |
Compared with SFM3300-D and AWM720P1, the FS1023-1001-DG uniquely combines wide 0–35 L/min range, dual analog/digital outputs, fast <5 ms response, and solid thermal isolation-making it optimal for medical and industrial systems demanding reliability, redundancy, and dynamic performance.

FAQ
What is the calibrated gas medium for FS1023-1001-DG flow accuracy specifications?
The FS1023-1001-DG is calibrated using nitrogen gas at 25°C and 1 bar pressure. Flow accuracy of ±1.5% typical is specified under these conditions. While validated for air use, actual accuracy in other gases (e.g., O₂, CO₂) requires system-level recalibration due to thermal property differences. The FS1023-1001-DG datasheet explicitly states nitrogen as the calibration standard, and users must account for gas-specific correction factors in non-nitrogen applications.
Does FS1023-1001-DG require external pull-up resistors for I²C communication?
Yes, FS1023-1001-DG requires external pull-up resistors on both SDA and SCL lines to VDD. Its I²C interface uses open-drain outputs, and the datasheet specifies that Rp resistors must be added externally-no internal pull-ups are integrated. Typical values range from 2.2 kΩ to 10 kΩ depending on bus capacitance and speed (100 kHz or 400 kHz). Failure to install pull-ups will prevent reliable FS1023-1001-DG I²C communication.
What mechanical interface does FS1023-1001-DG use for gas tubing connection?
The FS1023-1001-DG features molded barb fittings on both inlet and outlet ports, designed for soft tubing with a nominal 3/8-inch (9.5 mm) inner diameter. A clamp is recommended to secure the tubing over the barbs. The wetted housing materials include PPE+PS blend resin and Parylene coating, ensuring compatibility with air and nitrogen. No additional gaskets or adapters are included with the FS1023-1001-DG module.
Can FS1023-1001-DG operate outside the 0–85°C ambient temperature range?
No, FS1023-1001-DG is rated for ambient operation from 0°C to +85°C only. Absolute maximum storage temperature is 105°C, but functional operation beyond +85°C is not guaranteed and may degrade accuracy or reliability. The FS1023-1001-DG's thermal isolation and calibration are optimized for this range; extended high-temperature exposure risks drift in zero-point and span, and voids warranty coverage per Renesas' absolute maximum ratings table.
How is data integrity ensured during I²C reads from FS1023-1001-DG?
Data integrity is enforced via an 8-bit checksum transmitted after the 12-bit flow data bytes. The checksum equals the 2's complement of the 256-modulo sum of the two flow data bytes. Upon receiving data, the host must compute the sum of the two flow bytes and add it to the received checksum byte-if the result is 0x00, the FS1023-1001-DG data payload is valid. This mechanism detects single-bit and multi-bit transmission errors in the I²C stream.
