Interactive Calculators

Five real-time interactive calculators for sensor coverage planning, noise compliance assessment, power budget sizing, data storage estimation, and battery life prediction. All calculations update instantly as you adjust inputs.

Calculator 1 — Sensor Coverage & Node Count Estimator

Estimate the number of monitoring nodes required to achieve adequate coverage for your park area, based on deployment type, sensor spacing rules, and zone configuration.

1 ha = 10,000 m²
Typical: 4× √(area in m²)
Boundary: 100–300m | Indoor: 10–15m per node
Typical: 100–200 m² per node

Calculator 2 — Noise Compliance Level Checker

Assess whether measured noise levels comply with applicable standards. Enter measured Leq values for day and night periods and select the applicable zone type to instantly see compliance status and margin.

07:00–22:00 period
22:00–07:00 period
Class 2 meter typical: 1.5 dB
Measured without source
0, 3, or 6 dB if tonal content

Limits based on ISO 1996 and typical national standards. Adjust zone type for specific regulatory limits.

Calculator 3 — Field Station Power Budget Estimator

Calculate the total power consumption of a monitoring station and size the power supply, UPS backup, and solar panel accordingly. All values update in real time as you adjust device counts and power ratings.

Typical: 3–5 h/day
Typical: 80–90%

PSU sized at 150% of total load for thermal derating. Solar panel sized for daily energy ÷ peak sun hours ÷ efficiency. Battery sized for UPS backup hours.

Calculator 4 — Data Storage & Bandwidth Estimator

Estimate the data volume generated by your monitoring system and size the edge buffer, cloud storage, and network bandwidth accordingly.

Each sensor may have multiple channels
1 min = standard; 0.017 = 1 second
Typical: 8–32 bytes (timestamp + value + flags)
Typical time-series: 3–5×

Edge buffer sized for raw data. Cloud storage uses compressed size. Bandwidth calculated as average; peak may be 3–5× higher during bulk upload after outage recovery.

Calculator 5 — Battery Life Estimator for Wireless Sensors

Estimate the battery life of a wireless (LoRaWAN or NB-IoT) sensor node based on battery capacity, active current, sleep current, and duty cycle. Helps optimize reporting intervals for maximum battery life.

Typical D-cell: 19,000 mAh
Sensor + radio TX current
Measure + transmit time
MCU deep sleep + sensor standby
Lithium: 1–3%/year
Cold climate: 10–30% capacity loss
Replace when capacity reaches this %

Average current = (active_mA × active_s/cycle + sleep_µA/1000 × sleep_s/cycle) / cycle_s. Effective capacity adjusted for self-discharge and temperature derating. EOL threshold applied to usable capacity.
